写装置。[Claims for Utility Model Registration] A transfer drum that is installed opposite to a photoreceptor drum of an image forming apparatus and rotates at the same linear speed as the photoreceptor drum while supporting transfer paper on its circumferential surface during image formation, and the transfer drum. A transfer unit is formed by unitizing various parts attached to the drum and is fixed to the main body of the apparatus during image formation, and one end of the transfer drum is attached to the peripheral edge of the rotor of an outer rotor motor provided in the transfer unit. In the transfer device of an image forming apparatus, the transfer drum support device includes a transfer drum support device that supports the transfer drum and rotatably supports the inner peripheral surface of the other end by three rollers provided on a face plate fixed to the transfer unit. One of the three rollers of the device is supported by the face plate via a swingable bracket, and has means for urging the one roller outward in the radial direction of the transfer drum. transfer device.
