Abstract
A unit exclusive use power source is provided for a duplexer printing unit which is coupled to a color printer main body of an electrophotography apparatus. The unit exclusive use power source has a circuit for presenting an “on” state and “off” state of a supply of electric power to respective constituting components in the duplexer printing unit in accordance with an indication of a controlling device. When the color laser printer main body is in an electric power saving mode and when an abrupt duplex printing after release of the electric power saving mode is unnecessary, the controlling device enables an “off” state of the unit exclusive power source. Since an operation of the coupled duplexer printing unit is unnecessary, such as in the electric power saving mode time, the power source of the duplexer printing unit is presented to the “off” state. Thereby, the electrophotography apparatus satisfies electric power regulation value therefor.
