Abstract
An image forming apparatus includes a housing and a transfer unit. The transfer unit detachably attachable relative to the housing includes a drive roller, a driven roller disposed opposite the drive roller, a belt formed into a loop and entrained around the drive roller and the driven roller, a frame to support the shaft of the drive roller, and a support member to movably support the shaft of the driven roller to be parallel to an axial direction of the drive roller and movable in a first direction different from the axial direction. A positioning member disposed in the housing holds the shaft of the drive roller parallel, and a restriction member restricts movement of the driven roller in the first direction to keep the shaft of the driven roller parallel to the shaft of the drive roller as the transfer unit is mounted in the image forming apparatus.
