  • Patent number: 8346108
    Abstract: Disclosed herein is an image forming apparatus capable of avoiding positional interference between an electrical potential sensor and a developing device during the installation or separation of the developing device. The positional interference is prevented by moving the electrical potential sensor out of the movement path of the developing device in association with the opening/closing movement a cover for an access opening in the body of the image forming apparatus for the installation/separation of the developing device. A link device connects the cover and the electrical potential sensor to each other so as to cause the movement of the electrical potential sensor in linkage with the opening/closing of the cover. The link device serves as an anti-interference device that prevents the positional interference between the developing device and the electrical potential sensor.
