ABSTRACT:
According to this invention, the contact and separation conditions between an OPC drum and a charger roller are controlled by utilizing a tension spring, which is connected between a frame and a bearing through which the shaft of the charger roller extends, for separating a driving gear of the OPC drum and a driven gear of the charger roller by a predetermined distance in order that the OPC drum and the charger roller can be separated while the OPC drum is at standstill, in order to prevent the charger roller from deforming or contaminating the OPC drum. The force of the tension spring is overcome by the force generated by the driving gear engaging the driven gear to enable the OPC drum and the charger roller to again contact each other while the OPC drum is rotated.
