ABSTRACT:
An image forming apparatus has a chassis, a roller rotatably supported in the chassis, a motor for driving the roller in either of first and second rotational directions, a motive gear that receives driving force from the motor, a driven gear that meshes with the motive gear, and a pivot arm that is pivotably mounted on the motive gear and has an axle that rotatably supports the driven gear via a coil spring. The inner peripheral portion of the coil spring engages a first holder formed on the driven gear, while the outer peripheral portion of the coil spring engages a second holder formed on the pivot arm. It is possible to use a coil spring to pivot a pivot arm without increasing the number of components or the time required for assembly.
