<P>PROBLEM TO BE SOLVED: To provide a cleaning roller for a charging device capable of preventing both ends of winding start and finish of an elastic member from removing from a shaft, thus avoiding poor cleaning of a charging roller or uneven charge due to uneven cleaning. <P>SOLUTION: A cleaning roller is pressure-contacted to a charging roller that charges an image carrier to cleaning a surface of the charging roller. The cleaning roller comprises a shaft-shaped member, and a strip-shaped elastic member wound around the shaft-shaped member spirally at intervals. In the strip-shaped elastic member, volume per unit adhesive area at a portion for winding start or winding finish is smaller than volume per unit adhesive area at a portion adjacent thereto. <P>COPYRIGHT: (C)2012,JPO&INPIT |
