Title: Image forming apparatus
Inventor: HAYAKAWA AKIRA
IPC: G03G15/16
Filed: 2001-12-07
Abstract: <P>PROBLEM TO BE SOLVED: To shorten the first print time.  <P>SOLUTION: A charge injection layer is provided on the photoreceptor drum A, which enables the photoreceptor to be charged at almost the same electrical potential by the application of a DC voltage. The same polar bias as an electrostatic charge is applied to a transfer means until the electrostatic charge starting position on an image carrier arrives at a transfer position at least from a electrostatic charge start to the image carrier, and the charge injection layer on the photoreceptor drum is electrostatically charged. An image exposure means draws image information on the image carrier which has passed through the transfer position and the electrostatic charge position. Thereby, a pre-rotation process for stabilizing the potential by electrification of the image carrier can be shortened, and the density unevenness of an image caused by the difference of the potential by electrification can be reduced.  <P>COPYRIGHT: (C)2003,JPO
