PURPOSE:To almost eliminate blots of the white ground part of an image due to unequal charging and stably obtain a copy image of high picture quality, by forming a pressing roller peripheral face of an elastic material, and performing a linear abutment or face-abutment while running a belt-like abrasive member at the angle of 0 deg. to 87 deg. to a generating line of a charged roller. CONSTITUTION:The surface of a charged roller 11 is subjected to roughening by abutting of a belt-like abrasive member 12 on the surface of the charged roller 11 by a pressing roller 14. In this case, the peripheral face of the pressing roller 14 is formed of an elastic material. Moreover, the belt-like abrasive member 12 is linearly or facially abuts on this charged roller 11 while traveling at the angle of 0 deg. to 87 deg. to the generating line direction 19 of the charged roller 11. |
