Abstract
A counter reset arrangement employed in an image forming apparatus such as a photocopier which is provided with a cartridge removably mounted in a main body of the apparatus and internally accommodating at least a photoreceptor and a cleaning unit integrally, and a resettable counter securely mounted in the main body of the apparatus to detect a remaining service life of the cartridge. The counter reset arrangement includes a reset member movably disposed in the cartridge and having a first protruding portion pressed against at a first position when mounting the cartridge, by a cabinet provided in the apparatus and a second protruding portion formed to press against a reset pin disposed on the counter to reset it. The counter reset arrangement further includes a first plate-like member disposed inside the cartridge to bias the reset member towards its second position where the first protruding portion is kept out of contact with the cabinet, so that the reset member is shifted to its second position after the counter has been reset by the second protruding portion through movement of the reset member caused by the cabinet and a second plate-like member also disposed inside the cartridge to bias the reset member against the first plate-like member towards its first position so that the reset member can be returned to the first position.
