ABSTRACT:
A charging apparatus having a charging device for contact charging a rotatable member. The charging device rotates upon reception of a drive force from a drive force transmitting device. The axis of rotation of the charging roller and the axis of rotation of the photoreceptor drum intersect each other. It is a characteristic of the invention that a force received by the charging device from the drive force transmitting device and a force generated between charging device and the rotatable member are oriented in the same direction. With this arrangement, the thrust position of the charging device when the charging device is driven is stabilized.
