Abstract
While providing an easy access to a working space between a secondary transfer roller and an intermediate transfer belt, an image forming apparatus is capable of ensuring a working space wider than a rotation radius of the secondary transfer roller in a state that the rotation center portion is pivotally supported on the image forming apparatus side. In a state that a rotation center portion engages with a rotation center hole provided in a housing frame, a secondary transfer unit is rotated on the rotation center hole to position the secondary transfer roller with respect to a secondary transfer counter roller. When the rotation center portion, which is engaged with the rotation center hole, is disengaged accompanying the opening operation of the exterior door, the exterior door supporting the secondary transfer unit is capable of opening widely outward.
