ABSTRACT:
A cleaning device capable of reducing the apparatus and prolonging the service life of the cleaning blade is disclosed. The cleaning device includes a cleaning blade including an elastic blade, a pressing member disposed near the downstream side of the image carrier with respect to the elastic blade, and a driving mechanism for driving the pressing member so as to be in contact with and press the elastic blade. The driving mechanism operates so as to press the elastic blade in the upstream direction to separate the elastic blade from the surface of the image carrier for a while. Then, the driving mechanism operates to move the pressing member to be separated from the elastic blade so that the elastic blade is in contact with the surface of the image carrier.
