IMAGE FORMING DEVICE AND IMAGE FORMING METHOD USING ELECTROPHOTOGRAPHY

摘要

An image forming device comprising a photosensitive body having gamma of latent image of 3 or more, a charging means, an exposing means, a developing means, a transferring means, a cleaning means and a charge removing light source, characterized in that the image forming device further comprises a field applying means which applies an AC field with a frequency of 50 Hz - 1 kHz to a part of the photosensitive body which is excited by exposure with the charge removing light source. An image forming device is also disclosed. Thanks to the device and method, even if images are formed continuously using a high gamma electrophotography photosensitive body, high quality and high resolution images free from afterimages can be stably formed without a hysteresis phenomenon and sensitivity shift.
