Title: Developing device for electrophotographic image forming device
Inventor: HAYASHI KOJI
IPC: G03G15/08
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a high-definition image with no change with the lapse of time by carrying out the idling operation of a developing device when the defference between the voltage ratio obtained at the time of the final image formation and the voltage ratio obtained at the time of turning on a power source exceeds a reference value, and stopping the idling operation when the difference becomes the reference value or lower than the value. CONSTITUTION:This device is provided with a detecting part 13 which detects a voltage V0 applied to a developing roller 4 and a voltage V1 induced to a counter electrode 7 through a developer layer on the developing roller 4. A finally-detected voltage ratio RF=V1/V0, which is the ratio between the induced and applied voltages detected at the time of the final image formation, is stored in a storage part 15. A processing part 14 performs calculation for making a comparison between the initially-detected voltage ratio RM=V1/V0 and the stored finally-detected voltage ratio RF, the initially-detected voltage ratio RM being the ratio between the induced and applied voltages detected prior to the image formation after the power source is turned on. When the reference value A does not satisfy the relationship of RM-RF<=A, the idling operation of the developing device 2 is started. The idling operation of the developing device 2 is stopped after the initially-detected voltage ratio RM satisfies the relationship of RM-RF<=A. Thus, the high-definition image with no change with the lapse of time can be formed.
