an electrophotographic image forming apparatus forms an image on a photosensitive drum of a cartridge also containing , process means , and a memory with a contact . the apparatus includes a member movable between opening and closing positions ; a detector detecting closing of the movable member ; a connector having a contact movable between contact and separating positions an operator moving the connector from the separating to the contact position ; a holder engageable with the operator to hold the connector at the contact position ; a controller communicating with the memory through the connector after detection of a signal change from the detector when the movable member moves away from the closing position ; a releasor releasing engagement between the holding and operation members after the movable member moves from the closing position by a predetermined distance ; and an urger urging the connector in a direction away from the contact position toward the separating position .
