たことを特徴とする転写分離装置。 A transfer means for transferring the toner image formed on the photoreceptor onto a transfer paper; a separation means for separating the transferred transfer paper from the photoreceptor; a separation claw that can be freely moved toward and away from the separation claw; a claw driving means for moving the separation claw toward and away; a counting means for counting the number of jams at a separation position by the separation claw; and a control means for controlling the drive of the claw driving means. When copying is performed before the occurrence rate of jams counted by the counting means reaches a predetermined value, the claw driving means is driven on and off at a predetermined timing to bring the separating claw into contact with and away from the photoreceptor; . A transfer separation device, characterized in that during copying after a jam occurrence rate has reached a predetermined value, the pawl driving means is always driven to bring the separation pawl into contact with the photoreceptor.
