摘要:
An image forming apparatus includes a toner replenishing portion, a waste toner collecting portion, and a toner container. The toner container is attachable to the toner replenishing portion and the waste toner collecting portion. The toner container includes a first lever switchable between first and second positions, and a second lever switchable between third and fourth positions. The toner replenishing portion includes a first actuating portion configured to, while the toner container is being attached to the toner replenishing portion, prohibit an attachment of the toner container, and a second actuating portion configured to switch the second lever to the fourth position. The waste toner collecting portion includes a third actuating portion configured to, while the toner container is being attached to the waste toner collecting portion, prohibit an attachment of the toner container, and a fourth actuating portion configured to switch the first lever to the second position.
摘要:
The present invention provides a process cartridge mountable to an image forming apparatus, comprising an image bearing member, at least one process means acting on the image bearing member, and a detection member for detecting the presence/absence of developer supplied to the image bearing member on the basis of electrostatic capacity.
摘要:
A process cartridge detachably mountable to a main assembly of an image forming apparatus, the cartridge comprising a photosensitive member, a developing means for developing a latent image formed on the photosensitive member, a first frame containing the developing means; and a second frame coupled with the first frame, the second frame including a developer containing portion for containing a developer to be supplied to the developing means to develop the latent image, wherein the second frame is a selected one of plural secondary frames engageable with the first frame and having different developer containing capacities.
摘要:
The present invention is characterized by that a first frame for containing developer used with a developing operation, a second frame for supporting a developing means for developing a latent image formed on an image bearing member, and a third frame for supporting the image bearing member are made of the same material.

摘要:
The present invention provides a process cartridge mountable to an image forming apparatus, comprising a frame, an image bearing member, process means acting on the image bearing member, and a gripper for gripping the process cartridge. The gripper portion is provided on said frame at a position offset from a longitudinal center of the process cartridge toward a position where the frame is subjected to a greater mounting resistance generated by engagement between the process cartridge and a member on the main body, when the process cartridge is mounted to the image forming apparatus.
摘要:
The present invention relates to an image forming system and a process cartridge mountable thereon. A developing device can be separated into a first portion including a developing roller and a second portion including a toner containing member, and the second portion can be removably mounted on the cartridge. Thereby, it is possible to utilize the toner containing containers effectively without repeating the positioning of the developing roller with respect to a photosensitive member.
摘要:
A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.

An electrostatographic printing machine comprising a main frame and at least one unit insertable into and removable from said main frame for cooperative association therewith in producing prints, said main frame and said removable unit having at least one electrical connection to conduct electric current therebetween comprising two electrical contacting elements, one on each of said main frame and said removable unit a first element comprising a plurality of resiliently flexible conductive fibers arranged in a brush-like configuration and the second element comprising a substantially continuous conductive contact surface for electrical contact with said brush each of said contacting elements being connected to an electrical component.
摘要:
An image-forming apparatus includes: a first unit; a second unit opening and closing with respect to the first unit; an image-forming unit having a photosensitive member, a developing device, and a housing surrounding them; a holding device detachably holding the image-forming unit and attached to the second unit to move between a first and second positions; and an eraser device arranged at the second unit. The housing has a hole for connecting with an outer surface of the member. The eraser device is positioned outside the hole of the housing when the holding device is at the first position in opening the second unit, and in the hole thereof when the holding device is at the second position is closing the second unit. A method, in the apparatus, includes a first unit and a second unit opening and closing with respect to the first unit. The method includes the steps of: detachably attaching an image-forming unit to the second unit, the image-forming unit having a photosensitive member and a developing device therein; providing a hole for connecting with an outer surface of the member; fixedly attaching an eraser device to the second unit; holding the first unit at a first position when the second unit is opened, where the eraser device is confronted with the hole; and moving the first unit to a second position when the second unit is closed, where the eraser device is positioned in the hole.
