Title: Image forming apparatus and process cartridge
Inventor: MURAKAMI EISAKU
IPC: G03G15/08
Filed: 2002-11-25
Abstract: <P>PROBLEM TO BE SOLVED: To prevent mixing of colors and to suppress occurrence of image void due to use with time while employing the advantages of a no blade brush method.  <P>SOLUTION: Only reverse electrified toner T<SB>1</SB>is recovered by a brush roll 41 from transfer residual toner remaining on a photoreceptor drum 1. Normal electrified toner T<SB>0</SB>of the transfer residual toner is recovered by a developing device 5 after being passed through a contact range with an electrifying roll 3a as it is. The reverse electrified toner recovered by the brush roll is discharged to the photoreceptor drum 1 at a time other than at image formation. Solid lubricant 46 is brought into contact with the brush roll and the photoreceptor drum is coated with the lubricant by the brush roll. Thus, the mechanical attaching force of the toner to the photoreceptor drum surface is weakened and the toner can be appropriately transferred in a transfer range. Therefore, the occurrence of the image void can be suppressed.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-11-27
Abstract: <P>PROBLEM TO BE SOLVED: To realize a driving device which controls the static angle error (difference with actual step operation angle to theoretical step angle) of a stepping motor to minimum resolution of an angle detector.  <P>SOLUTION: The driving device has a driver of a stepping motor in which the motor rotates stepwise at every application of an external command pulse which has a micro step function which subdivides a basic step angle when a motor winding current which changes sinusoidally for every application of the external command pulse is made to flow. The motor performs progressive step rotation for every application of the external command pulse. In the driving device, an excitation angle generator for generating excitation angle which is used for generating a sine wave shape motor current from the external command pulse, and an angle detector for detecting rotor rotation angle, are arranged. When a rotor is stopped, position deviation is calculated which is difference between excitation angle (excitation position) and rotor angle (rotor position) which is detected with the angle detector, the position deviation is added to the excitation angle, and the excitation angle is updated. As a result, a rotor stopping position is corrected.  <P>COPYRIGHT: (C)2004,JPO
