摘要： A transfer assembly includes a counter member having a contact face, an engagement/disengagement unit to engage and disengage the image carrying face of image carrying member and the contact face of counter member using a cam, a pressure device to apply force to a transfer nip between the image carrying face and contact face, and a recording medium feed device to feed the recording medium to the transfer nip. When the cam is at a first rotation position, the image carrying face and contact face are separated, and when the cam is at a second rotation position, the image carrying face and contact face contact. Before the recording medium enters the transfer nip, the cam rotates from the first rotation position toward the second rotation position. After the recording medium enters the transfer nip, the cam is at the second rotation position to press the image carrying face with the contact face.

摘要： An image forming apparatus includes an endless intermediate transfer belt rotatably stretched over a plurality of rollers, and a detector to read a pattern on the intermediate transfer belt. One of the rollers includes a first portion disposed opposite an area on the intermediate transfer belt including a pattern passing position, and a second portion not including a pattern passing position. The first portion has a diameter smaller than that of the second portion thereof, and an elastic material is superimposed on the second portion only. The detector is disposed between a second roller disposed upstream of the first roller and a third roller disposed downstream of the first roller, and opposite the intermediate transfer belt.
