IPC: G03G21/00
Filed: 2007-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming device for controlling drive of a motor properly.  <P>SOLUTION: Toner patches for setting a developing motor driving current are developed on five photoreceptors. The toner patches are developed by the corresponding set values I1-I5 of the developing motor driving current. The toner patches are transferred to a transfer belt and detected by a toner density detection sensor for measuring a density level. When the value of the developing motor driving current is too low to rotate a developing roller, the developing motor steps out and the toner patches cannot be developed or sufficient density cannot be acquired. By detecting an increase or decrease in the amount of reflected light from the toner patches by the toner density detection sensor, the value of the developing motor driving current that prevents step-out of the motor and allows stable driving is determined and set to the device.  <P>COPYRIGHT: (C)2009,JPO&INPIT
