Abstract
An image forming apparatus is provided with a movable image bearing member, such as a movable amorphous silicon photosensitive member, and an image forming member forms an image on a surface of the image bearing member. The image on the surface of the photosensitive member is transferred to a transfer material. A separator electrostatically separates the transfer material from the photosensitive member after the image is transferred by the transferring member. The separator is supplied with an electric power having a voltage of a waveform which periodically changes. In one embodiment, the voltage waveform includes at least two sine waves of different frequencies superposed to lower the peak value of the first sine wave.
