Abstract:
A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The main assembly includes an output contact movable between electrical connecting and retracted positions, a displaceable member for moving the output contact, and an elastic function member for elastically urging the displaceable member to urge the output contact toward the retracted position. The cartridge includes an electrophotographic photosensitive drum, a process device actable on the drum, and a movable operation member engageable with a main-assembly fixed engageable member and with the displaceable member to move the output contact from the retracted to the electrical connecting position against the bias of the elastic function member, in interrelation with the movement of the displaceable member, after the engagement with the fixed engageable member when the cartridge is inserted into the main assembly. The cartridge also includes an input electrical contact.

A developer container for containing a developer includes: (a) a first detecting member which is an electrode member having a pair of input-side and output-side electrodes formed in parallel and in one plane at a predetermined interval for detecting capacitance between the electrodes and which has a measurement-side electrode that is in contact with the developer and a reference electrode that is out of contact with the developer; (b) a developer removing member for removing any developer adhering to a detection region of the first detecting member; and (c) a second detecting member formed of a conductive material for detecting capacitance between the second detecting member and a developer bearing member, wherein a main body of an electrophotographic image forming apparatus first detects the developer amount partway from the start of use of the developer container on the basis of detection information from the first detecting member, and then detects the developer amount on the basis of detection information from the second detecting member.
Abstract:
A memory cartridge for use with a printer, a copier, a word processor and other electronic equipment as an external memory. A connector corresponding to that of the equipment is provided on one end of a casing which accommodates a printed circuit board, which is loaded with memory devices. A plurality of memory cartridges may be connected to a buffer of the equipment via the individual connectors. A grounding plate for making contact with a grounding portion of the printed circuit board is disposed on the memory cartridge close to the connector. This reliably connects the memory cartridge to ground. Further, since which one of the memory cartridges is selected can be determined, it is not necessary for the equipment to be provided with buffers and related circuits in one-to-one correspondence to the memory cartridges.
