<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that can optimize an initial surface potential before charging a drum even when performing various discharge/separation sequences for enhancing image quality or even under various environments. <P>SOLUTION: The apparatus includes: an image carrier; a charging means for charging the surface of the image carrier; an electrostatic latent image forming means for forming an electrostatic latent image by exposing a charged surface of the image carrier surface according to image data; a developing means for processing visualization of the electrostatic latent image as a toner image using toner; a transfer means for transferring the toner image to a recording medium; a discharge means for eliminating charges by applying biases onto the recording medium charged by the transfer processing; and a pre-exposure means for performing discharge processing of residual charges remaining on the surface of the image carrier after transfer processing. The light emission quantity of the exposure means is varied depending on the magnitude of bias applied from the discharge means to the recording medium. <P>COPYRIGHT: (C)2007,JPO&INPIT |
