PROBLEM TO BE SOLVED: To solve the following problem: satisfactory cleaning performance to a spherical small-diameter toner is not ensured only by applying vibration to a cleaning blade. SOLUTION: A cleaning blade 20 to which vibration is applied in the cleaning unit 16 comprises a blade member 21, a vibration member 22 to which the blade member 21 is attached, a vibration applying means 23 attached to the vibration member 22, and a driving circuit 28 which drives the vibration applying means 23 according to a driving signal Pv with a resonance frequency of the blade member 21 and an image carrier 11 as a driving frequency, whereby a vibration amount of the blade member 21 is secured and cleaning performance is improved.
