摘要:
A process cartridge having an insertion construction for a connecting pin swingably supporting a developing unit where there are achieved an improvement in assembly property, a minimization of container deformation, and prevention of coming-off of the connecting pin due to a small press-fitting region. The connecting pin swingably supporting the developing unit is formed of a styrene-based resin composite, and, by injecting a terpene solvent from a cutout of a photosensitive drum unit frame to the outer periphery of the connecting pin, integral connection is effected between the photosensitive drum unit frame and the connecting pin, and further, between the photosensitive drum unit frame and a drum bearing member. Due to a press-fit portion between the connecting pin and the photosensitive drum unit frame, no terpene solvent flows to the developing unit side.

An image forming apparatus has a tray, which is able to be drawn out of the apparatus and on which a plurality of cartridges of different sizes can be mounted. A cartridge, being the largest in size among a plurality of process cartridges, is detachably arranged at a location at which it is first exposed to outside when a cartridge tray is drawn out. A developer storage portion of the largest cartridge has the largest capacity and stores a developer of a black color.

摘要:
In an image forming apparatus in which a tray, on which a plurality of cartridges of different sizes can be mounted, is able to be drawn out, a waste of space occurs. A cartridge (50k), being the largest in size among a plurality of process cartridges (50y, 50m, 50c, 50k), is detachably arranged at a location at which it is first exposed to outside when a cartridge tray (13) is drawn out. A developer storage portion having the largest capacity stores a developer of a black color.
摘要:
A developer container for an image forming apparatus, said developer container including a rotatable member; a container body for containing a developer; a sealing member, provided in the container body, for preventing leakage of the developer out of the container body; a sheet, provided in the container body, for contacting the rotatable member to guide the developer into the container body; a gap provided between the container body and the sealing member and covered by the sheet; a communication hole provided in the container body in fluid communication with the gap; packing material filled in the gap through the communication hole for preventing leakage of the developer through the gap.
