<P>PROBLEM TO BE SOLVED: To provide a photoreceptor cartridge capable of stabilizing a rotational speed of a photoreceptor drum while preventing an increase in the cost for the stabilization of the rotational speed, and to provide an image forming apparatus equipped with the same. <P>SOLUTION: A second cleaning gear 41 is engaged with a drum gear 29 and a first cleaning gear 40. Since the rotation of the drum gear 29 is transmitted to the first cleaning gear 40 through the second cleaning gear 41, a first cleaning roller 10 rotates in the same direction as the rotational direction of a photoreceptor drum 7 (against rotation) so that the surface of the first cleaning roller 10 moves, in a portion in contact with the photoreceptor drum 7, in a direction opposite to the moving direction of the surface of the photoreceptor drum 7. Therefore, frictional force is applied to the surface of the photoreceptor drum 7 from the first cleaning roller 10. The position of a rotation axis of the second cleaning gear 41 is fixed so that the distance of the rotation axis of the second cleaning gear 41 to a rotation axis of the drum gear 29 is constant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
