Patent ID: 8811867

Claim:
A transfer device, comprising: a plurality of rollers; a rotatable intermediate transfer belt wrapped around the plurality of the rollers; a transfer roller disposed in an inner loop of the intermediate transfer belt and facing a photoreceptor of an image forming apparatus within which the transfer device is installed, the photoreceptor disposed at an outer circumference of the intermediate transfer belt, to transfer an image formed on the photoreceptor when contacting the intermediate transfer belt; a frame that rotatably supports the transfer roller; and a cam that movably supports the frame to adjust a position of the intermediate transfer belt at a plurality of positions relative to the photoreceptor, the plurality of positions including a contact state in which the intermediate transfer belt having a first predetermined tension contacts the photoreceptor, a first separation state in which the intermediate transfer belt having a second predetermined tension separates from the photoreceptor, and a second separation state in which the intermediate transfer belt separates further away from the photoreceptor than in the first separation state, wherein, in the first separation state, the intermediate transfer belt is driven and a lubricating agent is applied on the intermediate transfer belt.
