摘要:
An image forming apparatus (10) includes a toner replenishing portion (40), a waste toner collecting portion (80), and a toner container (41). The toner container is configured to be attachable to and detachable from the toner replenishing portion and the waste toner collecting portion. The toner container includes a first lever (61) configured to be switchable between a first position (P1) and a second position (P2), and a second lever (62) configured to be switchable between a third position (P3) and a fourth position (P4). The toner replenishing portion includes a first actuating portion (101) configured to, during a process in which the toner container is attached to the toner replenishing portion, prohibit an attachment of the toner container, and a second actuating portion (121) configured to switch the second lever to the fourth position. The waste toner collecting portion includes a third actuating portion (102) configured to, during a process in which the toner container is attached to the waste toner collecting portion, prohibit an attachment of the toner container, and a fourth actuating portion (142) configured to switch the first lever to the second position.

摘要:
The size of an electrographic apparatus can be reduced, by simplifying the structural body (1) of the apparatus and increasing the accuracy of the structural body (1), and thereby increasing positional accuracy among respective components mounted therein. In such a small-side apparatus, a process cartridge (11) can be smoothly mounted without interfering with surrounding components by providing curved guide portions (30) in a frame (2) for supporting the cartridge (11).

A process cartridge detachably mountable to an image forming apparatus includes a device (4) contributable for forming an image; a developer accommodator (42); a sealing member (P) between the image forming device (4) and the developer accommodator (42), wherein the sealing member (P) is provided by injecting a liquid material which becomes an elastomer when it is solidified.
摘要:
An image forming apparatus includes a cleaning blade (6A) cleaning a photosensitive member (1) and a contact charging blade (2) for charging the photosensitive member. The contact charging blade is contacted to the photosensitive member with a frictional coefficient which is smaller than the frictional coefficient at which the cleaning blade is contacted to the photosensitive member. The photosensitive member and the blades are protected from wearing and damage even if the contact charging blade is contacted to such a portion of the photosensitive member which is free from residual matter due to the function of the cleaning blade. In addition, the service life of the contact charging blade can be expanded to be substantially equal to that of the cleaning blade, and therefore, the present invention is particularly effective when both of the blades are provided in a process cartridge detachably mountable into a main assembly of the apparatus.
