Abstract: A sheet conveyance apparatus is equipped with a first rotator, a second rotator conveying a sheet together with the first rotator, a cam member changing a position of the second rotator with respect to the first rotator, a drive unit rotating the cam member, and a load portion applying load on a rotation of the cam member. The load portion includes a contact member having a cam surface formed on a side surface in an axial direction of the cam member, an abutment member capable of abutting against the cam surface, and a biasing member biasing one of the contact member and the abutment member toward the other, a biasing force of the biasing member converted into a force, applying load to the rotating cam member, by the cam surface opposing to a rotating direction in which the cam member is driven by the drive unit.

Abstract: A sheet conveying apparatus is provided with a driving portion, and the driving portion is normally rotated, driving power from the driving portion is transmitted to a cam member through a transmitting portion. Then, one of a rotary roller pair is moved to another one. The sheet conveying apparatus further includes a restricting portion that restricts the cam member from turning in a direction opposite to a turning direction turned in response to a normal rotation of the driving portion.

Abstract: An image forming apparatus is capable of executing, in non-image formation, for example, in a sheet-to-sheet interval, a developer bearing member stop mode in which the developer conveyance by a development sleeve is stopped. For example, the apparatus turns off primary transfer bias in the sheet-to-sheet interval. Even if fogging toner is no longer supplied after the development sleeve drive is stopped, the apparatus can reduce frictional force variation between the photosensitive drum and the intermediate transfer belt to prevent speed variation of the photosensitive drum or the intermediate transfer belt, thus reducing the possibility of image unevenness and out of color registration.
