Abstract
A cleaning device includes a removing portion and a heater. The removing portion removes a toner held by an electrostatic force on a first surface of a latent image charge holding member. The latent image charge holding member includes a pyroelectric layer having a first surface on which the toner is deposited. The heater heats the pyroelectric layer to reduce the electrostatic force attracting the toner to the first surface of the pyroelectric layer, and the removing portion thereby removes the toner from the latent image charge holding member. In another embodiment of the cleaning device, the heater is incorporated in the removing portion which is a blade. In still another embodiment the cleaning device includes a heater and an ultrasonic vibrator is used as the removing portion.
