An image forming apparatus forming an image on a sheet, including: an exterior member movable with respect to an apparatus main body; a locking portion locking the exterior member to the apparatus main body such that the exterior member is not moved with respect to the apparatus main body; a display portion which is disposed on the exterior member and displays a state of the locking portion; and a light source turning on the display portion, in which the display portion includes a thin portion which is a part of the exterior member, has a thickness less than thicknesses of other portions of the exterior member, and transmits light from the light source.

IMAGE FORMING DEVICE
20230236537 · 2023-07-27 ·

To provide an image forming device that can prompt a user to check whether a waste toner container is completely attached.

Resolution means The image forming device includes a housing, an access cover attached in an openable/closable manner to the housing, a waste toner container attachable to the housing with the access cover open, and a lock lever that locks the waste toner container and the housing. The access cover includes a protruding portion protruding toward an interior of the housing. The lock lever transitions between a locked state and a pressed state of being pressed by the waste toner container, and, when in the pressed state, moves to a preventing position at which the lock lever blocks the protruding portion and prevents the access cover from closing, and, when in the locked state, moves to a retracted position at which the lock lever does not block the protruding portion.

Toner cartridge having front cover

An image forming apparatus includes a main body provided with a mounting portion and an interference member, and a toner cartridge inserted into the mounting portion. The toner cartridge includes a housing containing toner, a coupling portion, a front cover coupled to one end of the housing via the coupling portion, and a switching member to weaken a coupling force of the coupling portion by interfering with the interference member when the toner cartridge is mounted on the mounting portion.

Image forming apparatus facilitating detachment of toner cartridge from process cartridge attached to housing of image forming apparatus

An image forming apparatus includes a housing, a top cover having an opening, a process cartridge attachable to the housing, a toner cartridge attachable to the process cartridge, and an interlocking mechanism. The top cover is pivotally movable between a first position closing the opening and a second position opening the opening. In a state where the toner cartridge is attached to the process cartridge, the toner cartridge is pivotally movable between an attachment/detachment position where the toner cartridge is attachable to and detachable from the process cartridge; and a fixed position where the toner cartridge is fixed to the process cartridge. The interlocking mechanism is configured to pivotally move the toner cartridge to the attachment/detachment position when the top cover is moved to the second position, and to pivotally move the toner cartridge to the fixed position when the top cover is moved to the first position.

DETERMINING PRINT OFFSET

Disclosed is a print offset determining apparatus. The apparatus is to receive information indicative of a position of an imaging element relative to a binary ink developer when the binary ink developer comes into contact with the imaging element and determine an offset between the position of the imaging element and a reference position of the imaging element relative to the binary ink developer.
