DEVELOPING UNIT OF WET ELECTROPHOTOGRAPH PRINTING MACHINE

摘要

PURPOSE: A developing unit of a wet electrophotograph printing machine is provided to prevent toner from being absorbed by a cleaning roller and prevent rotary load of the cleaning roller by reducing an engagement quantity between the cleaning roller and a developing roller. CONSTITUTION: A developing solution container(81) contains developing solution. A developing roller(82) rotates with facing a photo conductor(10) in a state that the developing roller partially sinks under the developing water of the developing solution container. A cleaning roller(85) is rotated by being rubbed with an outer peripheral surface of the developing roller at a certain engagement quantity in a state the cleaning roller sinks under the developing water. The cleaning roller has a cell structure of which the size is 40-50 μm.
