  • Electrophotography with AC erasing of latent image
    Patent number: 6233416
    Abstract: An image-forming apparatus includes a photosensitive member having a gamma for latent image of 3 or more, electrification facilities, light exposure facilities, image development facilities, image transfer facilities, cleaning facilities, and a charge erasing light source which applies an alternating current electric field at a frequency of 50 Hz to 1 kHz to a portion of the photosensitive member which is excited through light exposure by the charge erasing light source. Images with high quality and high resolution can be stably formed without residual images, even when continuous image formation is performed by utilizing a high gamma electrophotographic photosensitive member.
