In the image forming apparatus, a controller makes a reference image formed on an outer circumferential surface of an image carrier and transferred to a belt. Then, uncollected toner of the reference image, which is part of after-transfer remaining toner of the reference image that has missed being collected so as to remain even after one-round rotation of the image carrier, is transferred to the belt. The controller measures a collectable toner quantity corresponding to an applied voltage of the cleaning roller on a basis of an uncollected toner quantity estimated based on a toner concentration of the uncollected toner, and executes such adjustment that the collectable toner quantity becomes equal to or larger than a maximum value of the after-transfer remaining toner quantity and moreover the applied voltage becomes equal to or lower than a maximum applicable voltage.
G03G 15/16 - Apparatus for electrographic processes using a charge pattern for transferring a pattern to a second base of a toner pattern, e.g. a powder pattern

In the image forming apparatus, a controller applies a collection voltage to a cleaning roller by a voltage application part in image formation process. The controller adjusts the collection voltage applied to the cleaning roller on bases of uncollected toner quantity of a toner image and residual charge of an image carrier, the uncollected toner being part of after-transfer remaining toner which results after formation of the toner image on an outer circumferential surface of the image carrier and transfer of the toner image onto a transfer-objective member, and which has missed being collected by the cleaning roller so as to remain even after one-round rotation of the image carrier.

A target selection portion selects one target attachment portion out of a plurality of attachment portions, and selects, when a detection state regarding a target storage unit attached to the target attachment portion out of a plurality of developer storage units changes from a developer-remaining state to a developer-empty state, a new target attachment portion as the target attachment portion. A notification processing portion executes, when a first notification mode is selected, empty state notification processing for outputting information representing the developer-empty state to a notification destination every time the developer-empty state of the target storage unit is detected. The notification processing portion executes, when a second notification mode is selected, the empty state notification processing when the developer-empty states of some of the plurality of developer storage units are detected.
An image forming apparatus includes a recording head, an endless belt, a plurality of through holes for flashing, a droplet receiver, and an anti-floating member. In the recording head, a plurality of nozzles capable of ejecting droplets onto a recording medium are arranged. The endless belt conveys the recording medium toward a position where an image is to be formed on the recording medium by the recording head. The through holes are formed in the endless belt. The droplet receiver receives flashing droplets having been ejected from the nozzles by flashing without contributing to formation of the image and having passed through the through holes. The anti-floating member prevents floating of end portions of the endless belt in a widthwise direction of the endless belt.
A management server stores box data received from an image forming apparatus as an export side, generates box configuration data that indicates the box data, upon receiving an import request of the box data from an image forming apparatus as an import side, transmits the box configuration data, and transmits the box data after the transmission of the box configuration data. The image forming apparatus as the import side transmits the import request, receives and saves the box configuration data and thereby registers the box configuration data to the box function, and receives and saves the box data after the receipt and the saving of the box configuration data. The image forming apparatus as the import side displays a list of the box data regardless of whether the box data has been received or not after registering the box configuration data.
An image forming system 100 includes a terminal 10, an image forming apparatus 20, and a network repeater 30. The image forming apparatus 20 includes a writer 24 that writes identification information of the network repeater 30 to a wireless communication tag 22. The terminal 10 includes a display device 12 that presents the identification information read from the wireless communication tag 22, a terminal's communication device 16 that is allowed to connect to and communicate with the image forming apparatus 20, and a transmitter 14 that transmits, to the image forming apparatus 20, the identification information selected by a user and an encryption key entered by the user. The image forming apparatus 20 configures a connection with the network repeater 30 based on the identification information and the encryption key transmitted from the terminal 10.
An arm is disposed between a body-side rotary shaft provided in a housing and a cover-side rotary shaft provided in a cover. The arm includes a body-side arm member with one end supported by the body-side rotary shaft, a cover-side arm member with one end supported by the cover-side rotary shaft, a connecting pin configured to connect the other end of the body-side arm member and the other end of the cover-side arm member, a body-side urging member configured to urge the body-side arm member and the cover-side arm member in respective directions of being folded, and a cover-side urging member configured to urge the cover-side arm member toward the cover. When the cover is closed, the body-side arm member and the cover-side arm member overlap each other in an axial direction of the connecting pin.
Methods and systems for managing print jobs among a plurality of printing devices. At least one desktop client is disclosed in the methods and systems. The at least one desktop client includes a database storing a desktop client application and a processor configured to collect data, transmit/receive data with a cloud-based server, choose a suitable printing device and direct a print job to the suitable printing device. The at least one desktop client can be a computing device, a mobile device, or a local server. The at least one desktop device may also be a multiple-function printing device (MFP).
