PROBLEM TO BE SOLVED: To provide a squeeze mechanism capable of eliminating image staining in a liquid developing system. SOLUTION: As for a squeeze roller 126 holding a photoreceptor belt 101 with a backup roller 118, an outer periphery part 124 on the outside is rotated and a fixed shaft 125 is on the inside. Electrode bodies A 111, B 112 and C 113 divided by an insulating supporting body 110 and insulated from each other are provided on the fixed shaft 125. The outer periphery part 124 is constituted of a hollow cylinder formed of a surface electrode 116 divided by a division insulating part 115. Plural sliding rollers 114 coming into rolling-contact with the outer periphery part 124 are rotatably fit on the surfaces of the electrode bodies A 111 to C 113. Developing bias voltage is applied to the electrode body A 111, and AC voltage is applied to the electrode body B 112. A cleaning electrode plate 123 opposed to the roller 126 is provided in a liquid reservoir 121, and bias in a forward direction is applied to the electrode body C 113. |
