Abstract
PURPOSE:To make wet type developing higher in speed by specifying the hardness, compression rate under pressed state, contact pressure force, etc. of the liquid- retentive porous elastic rotator for a developing roller at the specific values. CONSTITUTION:A wet type developing roller 1 is formed by a rigid central body 2, liquid-retentive porous elastic rotator 3, liquid-permeable flexible member 4 covering the rotator 3, etc. This rotator 3 has hardness of 10 to 40 in ASKER C- type hardness, is compressed 2 to 30% from the non-pressure state during developing and is pressure contacted to an electrostatic latent image carrier under contact pressure force of 100 to 800g/cm in line pressure. These cause the squeezing and supplying of liquid developer to be well accomplished through elastic compression and restoration of the elastic body 3 and the latent images to be developed at a high speed.
