Abstract
A service life determining system for determining the service life of an image bearing member or a magazine containing an image bearing member removably mounted on a main body of a copying apparatus and the like by counting the number of times of use or a period of time of use, including a resettable counter mounted on the main body of the copying apparatus for counting the number of times or the period of time the image bearing member is used and indicating the result, counter resetting means mounted on the image bearing member or the magazine containing the image bearing member for resetting the counter, and an actuator for actuating the counter resetting means. The actuator for the counter resetting means is operative to actuate the counter resetting means when a new image bearing member is mounted on the main body of the copying apparatus and destroyed when the new image bearing member or the magazine containing the new image bearing member has been set in a predetermined position after the counter resetting means is actuated, whereby the actuator is rendered in capable of actuating the counter resetting means again.
