Assignee: RICOH COMPANY, LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A heating device comprising:
a planar heater;
a rotator including a conductive layer, the rotator grounded via the conductive layer;
a pressure rotator having a conductive outer surface and being configured to press the rotator;
a heating device frame holding the pressure rotator;
a resistor;
a rectifier coupled in series to the resistor;
a discharger being in contact with the conductive outer surface of the pressure rotator and grounded via the rectifier, the resistor, and the heating device frame; and
another rectifier coupled to the conductive layer, the another rectifier configured to flow a current in a direction opposite to a current flowing through the rectifier, wherein the rectifier and the another rectifier are grounded via the resistor, and the rectifier is coupled in series to the discharger.
