Title: Image forming apparatus
Inventor: BETSUSHIYO YUUJI
IPC: G03G15/08
Filed: 2003-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus by which an excellent image is formed over a long term by preventing the occurrences of toner scattering, roughening and carrier sticking or the like while suppressing fluctuations of hue and density small.  <P>SOLUTION: A target value compared with the output value of patch detection is changed when output is not made within a specified range by providing a photosensor for detecting toner concentration in a developing unit. Thus, since the density of a reference patch image on a photoreceptor is constantly maintained by adopting a patch detection ATR system, the fluctuation of a toner electric charge amount is consequently reduced, and the stabilization of succeeding electrostatic transfer after development is attained, and the fluctuation of the hue is reduced by excellently changing the density, so that conventional problems such as the occurrences of the toner scattering, the formation of a roughened image and the carrier sticking at the time of the extreme fluctuation of the toner concentration in the developing unit are solved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
