摘要： PROBLEM TO BE SOLVED: To make it possible to minimize the meandering of a belt by controlling the driving of a steering mechanism in accordance with a belt edge learning value and the data on the belt edge position at every measured microsection. SOLUTION: The average position data on the belt edge at every microsection for one circumference of the belt is obtained with the section for detecting a rotation reference point and the rotation reference point as a start point in belt rotation control (S21, S22). A difference between the learning value deviation of the present position and the learning value deviation one point before is calculated in the present position of the belt edge. Decision is made from the change rate between the learning value deviation of the present position and the learning value deviation one point before (s24, 25) relating to the traveling state of the belt. The changing pulse number of a pulse motor is determined in accordance with the skew correction constant determined when the difference between the steering change offset constant determined by the state of the learning value deviation of the present position and the learning value deviation one point before is off the regulated range. The steering motor is rotated by as much as this value (S26, 27).

摘要： PROBLEM TO BE SOLVED: To provide a squeeze mechanism in a liquid developing system capable of removing toner shifting and adhering to a squeeze roller from a photoreceptor. SOLUTION: A solvent is supplied from a solvent channel 108 into a rear wall 110 provided on a withdrawing side from the contact part 106 of the squeeze roller 103 with a photoreceptor belt 101. Nine exit-side electrodes P1 to P9 are embedded in the wall 110. Voltage is applied to the electrodes P1 to P9 by a transfer voltage generation circuit 121 so that they may successively move in the rotating direction of the roller 103. Toner passing through the contact part 106 is electrophoresed in the solvent by the voltage applied to the electrodes P1 to P9, fed to a liquid reservoir 111 provided on the lower side of the roller 103 by the movement of the electrodes P1 to P9 to which the voltage is applied, and then discharged from a drain port 113 connected to the reservoir 111.
