Abstract
An image forming apparatus includes a cleaning device having a cleaning blade, including a toner image bearing member for bearing a toner image, a cleaning blade for frictionally removing residual toner remaining on the bearing member after a transferring process, and a device for applying vibration to the cleaning blade. Further, the vibration applied to the cleaning blade has a stead-state waveform. The vibration applying device may be a device for a vibration waveform having a frequency and an amplitude required for providing energy for obtaining a cleaning action, which vibration waveform is to be applied to the cleaning blade.
