Image forming apparatus forming offset preventive electric field according to static electricity removal current

摘要

Disclosed is an image forming apparatus capable of preventing the offset phenomenon and an electrostatic adhesion jam. The surface of a photosensitive body is uniformly charged by a corona charge device, and then an image of the reflected light from an original is projected on the photosensitive body to obtain an electrostatic latent image. Subsequently, a developer develops the latent image into a visible image with toner. The visible image is, then, electrostatically transferred onto a transfer medium by a charge means. After that, static electricity in the transfer medium is removed by a separation means so as to be separated from the photosensitive body and to be sent to a fixing device.
