IPC: G03G15/23
Filed: 2003-04-11
Abstract: <P>PROBLEM TO BE SOLVED: To prevent an image forming apparatus having a both-sided printing function from causing degradation in the life characteristics of a photoreceptor and to reduce printing failure caused by fog.  <P>SOLUTION: An ejection unit 7A is disposed at the downstream end of the main conveyance path 36 of a copying machine 1. The ejection unit 7A is provided with a shifter mechanism. A shifter function switches back and front between a paper insertion position relative to a photoreceptor drum 31b at the time of printing on the surface and a paper insertion position relative to the photoreceptor drum 31b at the time of printing on the back. Thereby, an area where the surface potential of the photoreceptor drum 31b increases is made narrow and an area where fog occurs is also made narrow. Thus, even in the event that minute displacement of a sheet of recording paper occurs in the conveyance position at the time of recording on a second paper or after, the recording paper is prevented from coming into contact with a fog area on the photoreceptor drum 31b. Accordingly, printing failure can be prevented.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
