A cartridge removably mountable to a main assembly of an electrophotographic image forming apparatus includes a developing member, a developer accommodating portion, a locking portion to engage a locking portion of the main assembly of the apparatus to prevent the cartridge from disengaging from the main assembly after mounting of the cartridge, a grip to be gripped by an operator when the cartridge is mounted to the main assembly, and a releasing portion to move the locking portion of the cartridge in interrelation with a movement of the grip which is moved when the operator grips the grip to disengage the cartridge from the main assembly of the apparatus. The locking between the locking portion of the cartridge and the locking portion of the main assembly is released by the movement of the locking portion of the cartridge.

A cartridge detachably mountable to a main body of an image forming apparatus, includes a developing frame, a developer carrying member provided in the developer frame and adapted to hold and carry developer, a developer containing container for containing the developer and for supplying the developer to the developer frame, a seal member for unsealably sealing an opening portion through which the developer is supplied from the developer containing container to the developing frame, a rotary member for supplying the developer toward the developer carrying member, a first drive transmitting device for effecting drive transmission between the developer carrying member and the rotary member, and a second drive transmitting device for transmitting the driving to the seal member to unseal the seal member.
摘要:
A method of reattaching a toner seal to a toner frame having a developer containing portion for containing a developer therein, a developer supplying opening for supplying the developer therethrough from the developer containing portion, in order to seal the developer supplying opening, which method includes (a) the detaching step of detaching the already taken-up toner seal from a take-up spool for taking up the toner seal, (b) the sticking step of sticking the toner seal on the toner frame so as to seal the developer supplying opening, (c) the folding-back step of folding back the toner seal from the end portion of the stuck portion of the toner seal, and (d) the attaching step of attaching the free end portion of the folded-back toner seal to the take-up spool for taking up the toner seal to unseal the developer supplying opening so that the operation of a detecting lever for detecting that a predetermined amount of the toner seal has been taken up to unseal the developer supplying opening may be restricted by the toner seal.

A cartridge detachably mountable to the main assembly of an image forming apparatus includes a developing frame provided with an opening; a developer carrying member in the opening to carry developer; a developer containing portion for storing developer, the developer containing portion supplying developer to the developing frame through the developer supplying opening; a sealing member for removably sealing the developer supplying opening; and a driving source substantially exclusive for providing the force for opening the sealing member.
摘要:
The information storing medium has a substrate, a storing element, provided on the substrate, for storing information, a protecting portion, covering the storing element, for protecting the storing element, an electrical contact point that is provided beside the protecting portion on a side of the substrate, on which the storing element is provided, and is electrically connected to the storing element, and a sliding region that is provided on the electrical contact point. In the information storing medium, when the storing medium is mounted on the apparatus main body, the electrical contact point contacts a main body electrical contact point provided on the apparatus main body. Also, when the electrical contact point and the main body electrical contact point contact each other, the main body electrical contact point slides on the electrical contact point in the sliding region.
