Abstract
A bearing detachably and rotatably holds a photoconductor. A bearing holder firmly holds the bearing. A rotating lever is provided on a rotation axis of a photoconductor between the photoconductor and the bearing holder. The bearing holder and the rotating lever are provided with many protrusions at regular intervals. At a first relative position of the bearing holder and the rotating lever, the protrusions on the bearing holder are located in between the protrusions on the rotating lever. At a second relative position of the bearing holder and the rotating lever, the protrusions on the bearing holder ride on the protrusions on the rotating lever thereby pushing the photoconductor away from the bearing and detaching the photoconductor from the bearing.
