摘要： A rear end plate having openings is bonded to a rear end portion of a transfer film through urethane sponge. To attach the rear end portion of the transfer film to a coupling member of a frame of a transfer material carrying body, restricting portions of respective restricting members are fixed to the coupling member through the respective openings of the rear end plate. The restricting portions of the restricting members abut the top face of the rear end plate so as to restrict a radial movement of the rear end plate and allow its circumferential movement.
