[Problem] To enable positioning with respect to a developing device or an image forming apparatus in accordance with an attachment operation, while transporting, in an axial direction of a rotation axis of an agitator, toner transported by the agitator. [Solution] This toner cartridge 1 comprises a casing 2, an agitator 3, an auger 4, a first protrusion 5, and a second protrusion 6. The casing 2 includes a first toner-housing part 2A, a second toner-housing part 2B, and a first opening 2C. The agitator 3 transports a toner from the first toner-housing part 2A to the second toner-housing part 2B. The auger 4 transports the toner from the second toner-housing part 2B to the first opening 2C in a first direction. The first protrusion 5 and the second protrusion 6 are separated from one another in the first direction, and are positioned with respect to a developing device 31 when the toner cartridge 1 is attached to the developing device 31. The auger 4 and the first opening 2C are located between the first protrusion 5 and the second protrusion 6.
A developing cartridge 1 includes a casing 10 configured to accommodate developer therein and extending in the first direction. Further, the developing cartridge 1 includes: a coupling 41 positioned at one side of the casing 10 in the first direction; a detection gear 52 positioned at another side of the casing 10 in the first direction; and a storage medium 61 including an electric contact surface 611 positioned at the one side of the casing 10 in the first direction. The detection gear 52 is rotatable about a rotation axis 85 extending in the first direction. The coupling 41 is rotatable about a rotation axis 83 extending in the first direction. Since the detection gear 52, and the coupling 41 and the electric contact surface 611 are disposed on opposite sides of the casing 10 in the first direction, an endface of the casing 10 in the first direction can be made small.
The structure is provided in which friction of an electric contact surface is reduced when a developing cartridge is attached. A developing cathidge has a casing configured to accommodate developer therein; a storage medium 61 including an electric contact surface 611; a holder 62 holding the electric contact surface 611; an elastic member 73. The elastic member 73 is configured to be compressed or expanded in the first direction between a first state and a second state which is more compressed than the first state. The outer surface of the holder 62 holding the electric contact surface is positioned at the first position when the elastic member 73 is in the first state, and the outer surface is positioned at the second position when the elastic member 73 is in the second state. Thus, a position of the outer surface of the holder 62 holding the electric contact surface 611 is changed in the first direction. Accordingly, friction of the electric contact surface 611 can be reduced when the developing cartridge is attached.
The structure is provided in which friction of an electric contact surface is reduced when a developing cal ___________________________________ tiidge is attached. A developing cartridge has a casing configured to accommodate developer therein; a storage medium 61 including an electric contact surface 611; a holder 62 holding the electric contact surface 611; an elastic member 73. The elastic member 73 is configured to be compressed or expanded in the first direction between a first state and a second state which is more compressed than the first state. The outer surface of the holder 62 holding the electric contact surface is positioned at the first position when the elastic member 73 is in the first state, and the outer surface is positioned at the second position when the elastic member 73 is in the second state. Thus, a position of the outer surface of the holder 62 holding the electric contact surface 611 is changed in the first direction. Accordingly, friction of the electric contact surface 611 can be reduced when the developing cartridge is attached.
In a developing cartridge having the electric contact surface, rubbing of the electric contact surface is reduced. The developing cathidge has a casing 10 accommodating developer therein; a developing roller 30; a storage medium 61 having an electric contact surface; and a holder 62 holding the electrical contact surface. The holder 62 is movable relative to the casing 10 in a second direction. Therefore, the position of the casing 10 in the second direction can be changed without changing the position of the electrical contact surface in the second direction. Accordingly, the position of the case 10 can be changed, while the contact condition of the electrical contact surface being maintained, during a removing operation after the developing cartridge 1 has been attached. As a result, rubbing of the electrical contact surface can be reduced.
A developing cartridge includes: a casing configured to accommodate developer therein; a storage medium including an electric contact surface; a holder holding the electric contact surface; and an elastic member. The elastic member is configured to be compressed or expanded in the first direction between a first state and a second state which is more compressed than the first state. The outer surface of the holder holding the electric contact surface is positioned at the first position when the elastic member is in the first state, and the outer surface is positioned at the second position when the elastic member is in the second state. Thus, a position of the outer surface of the holder holding the electric contact surface is changed in the first direction. Accordingly, friction of the electric contact surface can be reduced when the developing cartridge is attached.
In order to reduce rubbing of an electrical contact surface in a developing cartridge having the electrical contact surface, this developing cartridge 1 has: a case 10 housing a developing agent therein; a developing roller 30; a storage medium 61 having an electrical contact surface; and a holder 62 holding the electrical contact surface. The holder 62 holds the electrical contact surface on an outer surface in a third direction intersecting the electrical contact surface. The holder 62 is movable in a second direction, relative to the case 10. As a result, the position of the case 10 in the second direction can be changed without changing the position of the electrical contact surface in the second direction. Accordingly, the contact state of the electrical contact surface can be maintained and the position of the case 10 changed, during a separation operation after the developing cartridge 1 has been attached. Rubbing of the electrical contact surface can be reduced as a result.
