To provide a cleaning device which does not cause failure in cleaning by electrostatic removal even when a polymerized toner is used and can stably retain its cleaning performance over a prolonged period of time.

The cleaning device 6 has a conductive toner removing means to electrostatically remove a toner on an image carrier 1 by applying a DC voltage whose polarity is reverse to that of the toner by electrostatic charge or a bias obtained by superimposing AC on DC below a discharge start voltage, wherein the toner removing means comprises a multilayer resilient roller 61 and the cleaning device 6 is provided with a metal blade 63 which removes a toner recovered by the resilient roller 61.
