摘要： An image forming apparatus includes a casing, an image forming unit movable between an accommodated position and a shifted position, an actuator, an urging member, a cam, and a contact portion. The actuator includes a pivot shaft and a protrusion protruding therefrom. The protrusion at a standby position crosses a conveyance path and is contactable with a sheet conveyed along the conveyance path. When the image forming unit is at the accommodated position, the contact portion and the cam contact each other and maintain the protrusion at the standby position against an urging force of the urging member. As the image forming unit moves from the accommodated position to the shifted position, the contact portion and the cam move away from each other such that the protrusion pivots from the standby position, by the urging force, to a retracted position at which the protrusion is retracted from the conveyance path.

摘要： A sheet conveying apparatus includes a conveying roller, a pinch roller, a holding member, and a pressing device. The pinch roller includes a roller shaft and a roller body rotatable relative to the roller shaft. The roller shaft includes a first end portion and a second end portion. The holding member holds the roller shaft movably in a first direction. The pressing device presses the roller shaft in a pressing direction such that the roller body is pressed against a peripheral surface of the conveying roller. The first end portion of the roller shaft has a first contact surface being a planar surface. The second end portion of the roller shaft has a second contact surface being a planar surface. The roller shaft is disposed such that the first contact surface and the second contact surface are oriented in the pressing direction.
