<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing banding of an output image. <P>SOLUTION: In the image forming apparatus, the tip part of an abutment pin 46 of an LPH 20 abuts on a second positioning part 72 separated by 40 to 55 degrees along the circumferential direction of an outer circumferential surface of a bearing 52 in the opposite direction with respect to the rotational direction (the direction of an arrow B) of a photoreceptor drum 16 from a first positioning part 70 where a developing roller 24 is positioned. The second positioning part 72 where the abutment pin 46 of the LPH 20 abuts thereon is the minimum deformation position where the deformation of the bearing due to a load of a developing device 22 is at the minimum. The LPH 20 exposes the photoreceptor drum 16 in a stable state without vibration, thereby suppressing the banding of an output image. <P>COPYRIGHT: (C)2010,JPO&INPIT |
