A process cartridge detachably mountable to a main assembly of an image forming apparatus includes a frame; an image bearing member; a developing device; a toner accommodating device for accommodating toner to be supplied to said developing device; opening for supplying to said developing device the toner in said toner accommodating device; a toner seal removably mounted at said opening to close it; a gap in said frame to permit pulling of said toner seal; an elastic sealing member in contact with said toner seal to prevent leakage of the toner through the gap; wherein said toner seal is constructed such that said toner seal is out of contact with an end of said elastic sealing member upon pulling of said toner seal.
摘要:
A process cartridge that is detachably mountable to an image forming apparatus contains a photosensitive drum acting as an image bearing member and having opposed first and second ends. A developing roller and a charging roller are also provided in the process cartridge. A developing bias conductive member and a grounding conductive member are supplied at the first end of the drum in a direction perpendicular to a movement direction of the drum, and a charging bias conductive member for the charging roller is provided adjacent the second end of the drum.

A process cartridge detachably mountable relative to a main assembly of an image forming apparatus includes an image bearing member; a process device actable on the image bearing member; an elastic device; a receptor for receiving a force against an elastic force of the elastic device in contact with the main assembly when the process cartridge is mounted to the main assembly of the image forming apparatus; where when the process cartridge is to be taken out of the main assembly of the image forming apparatus, the elastic device displaces the process cartridge by the elastic force of the elastic device.
摘要:
A remanufacturing method of a process cartridge detachably mountable to an image forming apparatus includes disassembling the process cartridge into a first frame having a developer accommodating portion for accommodating a developer and a second frame having a developer carrying member for carrying the developer supplied from the developer accommodating portion toward an image bearing member, thus exposing an opening of the first frame for permitting movement of the developer from the first frame to the second frame; removing residual which is resulted from a covering member having been used for sealing the opening and which remains around the opening, wherein the covering member has a sealing portion for sealing the opening and an extension for permitting the sealing portion to be torn with a part thereof remaining around the opening to open the opening, by pulling the extension, wherein the residual is a part of the sealing portion; mounting a fresh covering member to seal the opening; then supplying the developer accommodating portion with a fresh developer; and then engaging the first and second frames together.

A process cartridge includes a rotatable rotary member having a plurality of bearing attachment portions to which bearings are attachable. The plurality of bearing attachment portions are provided on the rotary member with different diameters. A method of reusing a rotation member that is supported at one of a plurality of coaxial rotation surfaces having different diameters includes detaching one of a plurality of bearing members that supports the rotation member at the one of the plurality of coaxial rotation surfaces. Another of the plurality of bearing members is then attached at a corresponding other of the plurality of coaxial rotation surfaces that has a different diameter than the one of the plurality of coaxial rotation surfaces.
