Abstract:
1. An image forming apparatus configured to form an image on a sheet, comprising: a piece of endless belt; a driving roller, around which the endless belt is strained, the driving roller being configured to move the endless belt in circulation; a driven roller, around which the endless belt is strained, the driven roller being configured to rotate along with the circulation of the endless belt; a first bearing arranged on a first-side end of the driven roller along an axial direction, the axial direction corresponding to a rotation axis of the driven roller, and configured to support the driven roller rotatably, the first bearing being configured to be movable while supporting the driven roller rotatably; a resilient member configured to apply a resilient force, which tends to separate the driven roller apart from the driving roller, to the driven roller; and a frame comprising a first guide, the first guide being configured to guide the first bearing to move in an inclined direction, which inclines with respect to a virtual line extending through a rotation axis of the driving roller and the rotation axis of the driven roller, wherein a strained plane is formed by part of the endless belt moving directly from the driving roller to the driven roller and the first guide is formed to incline to be closer to the strained plane as the first guide extends farther from the driving roller.
