Title: Image forming apparatus
Inventor: SUZUKI HIROHARU
IPC: G03G15/09
Filed: 2002-01-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which prevents the deviation of toner to a rear end while achieves improvement of fine linear reproducibility, prevention of a white spot phenomenon at the rear end, prevention of the reduction of a density in an image and prevention of a poor image.  <P>SOLUTION: A main magnetic pole position is deviated by 2(°) to the upstream of a development sleeve surface moving direction. Thus, the nap of a developer is turned to the upstream side by 2(°) compared with a conventional nap to thereby prevent the toner deviation to the rear end, which restricts agent accumulation at the rear end of a main magnetic pole. As the adverse effect of deviating the main magnetic pole position to the upstream of the development sleeve surface moving direction, the nap of the developer is deviated from a development nip too much to shorten a sliding time with a photoreceptor and also reduce a density at the center of the image owing to the shortage of a toner supply amount to an electrostatic latent image. Thus, the deviation range of the main magnetic pole position is made to be ≤6(°), the reduction of the density at the center of the image is evaded and, then, the excellent image is obtained.  <P>COPYRIGHT: (C)2003,JPO
