Abstract:
An image forming apparatus includes a photosensitive member, a charging roller, a cleaning roller, an urging member and an image forming portion. The charging roller has an outermost surface layer including an electroconductive resin material, first surface particles having an average particle size of more than 7 μm and less than 30 μm and second surface particles having an average particle size of more than 2 μm and less than 6 μm. The first and second surface particles are dispersed in the electroconductive resin material so as to form first projections and second projections, respectively. The cleaning roller cleaning roller includes a shaft potion and an elastic cleaning portion extending helically around the shaft portion and having a rectangular cross-section perpendicular to an extending direction thereof.

Claim (Index 9):
A cartridge detachably mountable to an image forming apparatus, said cartridge comprising:\n a photosensitive member; a charging roller contacting said photosensitive member and configured to electrically charge said photosensitive member by being supplied with a voltage, wherein said charging roller has an outermost surface layer including an electroconductive resin material, first surface particles having an average particle size of more than 7 \u03bcm and less than 30 \u03bcm and second surface particles having an average particle size of more than 2 \u03bcm and less than 6 \u03bcm, and wherein said first surface particles and said second surface particles are dispersed in said electroconductive resin material so as to form first projections and second projections, respectively, on a surface of said charging roller; a cleaning roller contacting said charging roller and configured to clean a surface of said charging roller, wherein said cleaning roller includes a shaft potion and an elastic cleaning portion extending helically around said shaft portion and having a rectangular cross-section perpendicular to an extending direction thereof; and an urging member configured to urge said cleaning roller against said charging roller.
