摘要： In an image forming apparatus, a moving member is provided with a first engagement member. A lever is provided with a second engagement member to engage and disengage the first engagement member provided in the moving member. The lever moves between a predetermined first position and a second position different from the first position to move the moving member in such a manner that when the lever is at the first position, a transfer member reaches a contact position at which the transfer member is pressed against an image carrier via a belt, and when the lever is at the second position, the transfer member reaches a separation position at which the transfer member separates from the image carrier.

摘要： An image forming apparatus includes an intermediate transfer belt, a photosensitive belt, a primary transfer roller, a secondary-transfer opposing roller, and a secondary transfer roller. The photosensitive belt comes into contact with a surface of the intermediate transfer belt to form a primary transfer nip. The secondary-transfer opposing roller comes into contact with the surface of the intermediate transfer belt to form a secondary transfer nip. The closest distance between a surface of the photosensitive belt and that of the primary transfer roller is greater than the thickness of the intermediate transfer belt. A toner image on the intermediate transfer belt is transferred onto a recording sheet at the secondary transfer nip while a transfer bias is applied to the secondary transfer roller.
