发明名称 IMAGE FORMING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of easing influence of a member pressed against a photosensitive drum and of improving image quality. <P>SOLUTION: This image forming apparatus comprises a charging roller 22, a developing roller 24, a cleaning blade 28, and a transfer roller 16 as pressure members arranged so as to be pressed against the rotating and driving photosensitive drum 21. These pressure members are arranged at positions where the resultant force of a pressing force P<SB>n</SB>from the presssure members pressed against the rotating/driving photosensitive drum 21 and a frictional force U<SB>n</SB>of the pressure members and the photosensitive drum 21 is smaller than a predetermined value at the rotation center axis of the photosensitive drum 21. <P>COPYRIGHT: (C)2009,JPO&INPIT
