Claims

[Scope of utility model registration request]

A cleaning device having a cleaning blade that removes toner on a photoconductor by contacting the photoconductor, the cleaning device includes a support member that supports the cleaning blade so as to be movable toward and away from the photoconductor, and a support member that rotates the support member. and a pulse motor that rotates the support member in a direction opposite to the direction of rotation by the pulse motor by an urging member having a force slightly larger than the self-holding force of the pulse motor when the pulse motor is not in operation. 1. A cleaning device comprising a driving means for driving a cleaning blade in a reverse direction by driving the cleaning blade in a reverse direction.
