Abstract
The transfer device transfers a toner image to a recording medium. The recording medium passes through a nip portion formed by a belt roller which is disposed on a main body of an apparatus and a transfer roller which is disposed on an opening and closing cover. The opening and closing cover opens and closes an opening of a main body of the apparatus. The main body includes a positioning member which positions the transfer roller which moves according to a closing operation of the opening and closing cover, to a predetermined distance with respect to the belt roller. The main body also includes an engaging member which engages with the transfer roller and pushes the transfer roller toward a positioning position of the positioning member, by being urged by a pressurizing spring.
