IPC: G03G15/10
Filed: 2002-10-28
Abstract: <P>PROBLEM TO BE SOLVED: To prevent wasteful consumption of a liquid carrier.  <P>SOLUTION: A developing roller 31 is movably supported in the direction where it is brought into contact with a photoreceptor 11 and separated therefrom. For example, when an actuator comprising a solenoid or a motor is driven by a contact/separation drive part 118, it reciprocates between a contact position and a separation position. The contact position is a developing position where liquid developer held on the developing roller 31 comes in contact with the photoreceptor 11 and toner is supplied to the photoreceptor 11. The separation position is a position where the liquid developer is not in contact with the photoreceptor 11. When two-sheet control in which images for the two sheets are transferred to one round of an intermediate transfer belt 41 is performed but the image for the second sheet is not transferred, the developing roller 31 is retracted to the separation position during a period that corresponds to the non-image transfer area.  <P>COPYRIGHT: (C)2004,JPO
