Abstract

PURPOSE: To prevent damage of a transfer sheet, by contacting the transfer material around a transfer roller with a toner image holding material of photoreceptor only during copying.
CONSTITUTION: The figures show a state of transfer roller 20 apart from photosensitive drum 9 and a state of roller 20 in contact with drum 9. Rising part 41A of the first lever 41 is mechanically engaged with stepped part 49A of the second lever 49, the first and second solenoids 48, 53 are actuated at the same time for a short time in response to a copy starting signal fed at a state of roller 20 kept apart from drum 9 to disengage levers 41, 49, and to contact roller 20 with drum 9, thus permitting a prescirbed copying process to be carried out. In response to a copy end signal, solenoid 48 is energized for a short time to separate roller 20 from drum 9.
