A color printing system manages ICC profiles by controlling ink use without performing the ICC profile creation operations. To obtain an ink limit for an ICC profile, a table associated with the ICC profile is parsed to determine the ink limit. The ink limit is decreased or increased. For an ink limit decrease, a color over the decreased ink limit is adjusted to meet the new ink limit. The ICC profile is updated accordingly. For an ink limit increase, the combination of primary colors are boosted by a percentage amount. Checks are made with regard to the volume-based ink limit and an quality check operation to accepted the boosted amount. The ICC profile is updated accordingly.

A control portion (8b) derives an amount of deviation between the discharge position and a discharge reference position based on a detection result of the discharge position detecting portion (54, 8a). Furthermore, the control portion (8b) corrects a conveying position of the sheet in a sheet conveying portion according to the amount of deviation.
B65H 7/10 - Controlling article feeding, separating, pile-advancing, or associated apparatus, to take account of incorrect feeding, absence of articles, or presence of faulty articles by feelers or detectors responsive to presence of faulty articles or incorrect separation or feed responsive to incorrect side register

An image forming apparatus includes an image carrying member, a charging device, an exposure device, a developing device, a control section, and a temperature detecting device. The developing device includes a developer carrying member having an outer circumferential surface on which a toner layer is formed, and a regulation blade that regulates a thickness of the toner layer. The control section executes speed reduction control to reduce a rotation speed of the developer carrying member at a time of warming-up. When a printing operation to be performed after the warming-up is intermittent printing and an interval of the intermittent printing is not less than a prescribed time or a temperature detected by the temperature detecting device is not more than a prescribed temperature, the control section reduces the rotation speed of the developer carrying member in the speed reduction control to a second speed lower than the first speed.
An image forming apparatus includes an image carrying member, a charging device, an exposure device, a developing device, and a control section. The developing device includes a development container for containing a non-magnetic one-component developer composed only of a toner, a developer carrying member having an outer circumferential surface on which a toner layer is formed, and a regulation blade that regulates a thickness of the toner layer. The control section executes speed reduction control to reduce a rotation speed of the developer carrying member at a time of warming-up before image formation to a first speed lower than a reference speed at a time of the image formation. In the speed reduction control, the control section raises the rotation speed of the developer carrying member at a first acceleration rate until the first speed is reached from a state where rotation of the developer carrying member is stopped.
An image forming apparatus is capable of correcting a lateral deviation and/or a skew of a sheet. A pair of conveying rollers convey the sheet to a transfer position of an image. An image sensor reads the sheet on an upstream side of the transfer position in a sheet conveying direction. A control device senses a foreign substance on a reading surface of the image sensor as well as calculate a lateral deviation amount and/or a skew amount of the sheet based on an output signal of the image sensor.

An inkjet ink contains a quinacridone pigment, a resin, and an aqueous medium. A 50-fold dilution of a supernatant obtained by centrifugating the inkjet ink at 1,050,000 G for 3 hours has a phosphorous concentration of at least 1.0 ppm and no greater than 6.0 ppm. On an ultraviolet-visible absorption spectrum of the supernatant, a first peak appears at a first absorbance of at least 0.16 and no greater than 0.40. The first peak is a maximum peak in a wavelength range of the ultraviolet-visible absorption spectrum of at least 300 nm and no greater than 340 nm. On the ultraviolet-visible absorption spectrum of the supernatant, a second peak appears at a second absorbance of at least 0.15 and no greater than 0.80. The second peak is a maximum peak in a wavelength range of the ultraviolet-visible absorption spectrum of at least 400 nm and no greater than 490 nm.
An inkjet ink contains a pigment, urethane resin particles, polyolefin resin particles, dipropylene glycol monomethyl ether, propylene glycol, and water. The urethane resin particles have a percentage content of at least 2.5% by mass and no greater than 9.0% by mass. The polyolefin resin particles have a percentage content of at least 2.5% by mass and no greater than 9.0% by mass. The dipropylene glycol monomethyl ether has a percentage content of at least 4.0% by mass and no greater than 25.0% by mass. The propylene glycol has a percentage content of at least 9.0% by mass and no greater than 35.0% by mass.
