Title:
NEGATIVE PRESSURE SUCKING TYPE ROLLER DEVELOPING DEVICE
Document Type and Number:
Japanese Patent JPH0413169
Kind Code:
A
Abstract:

PURPOSE: To simplify structure and to attain the miniaturization of this device by controlling the rotation of a developing roller while a sucking pump is operated after development is finished with a control means, carrying a recording medium sheet, removing a developing liquid from the surface of the recording medium sheet, and drying a recording surface.

CONSTITUTION: The sucking pump 39 which sucks the developing liquid inside a developing liquid storing unit 38 by a negative pressure action, supplies it to a developing head, and then, returns it to the developing liquid storing unit 38, and a control means 44 which controls the sucking pump 39, a developing roller driving device 43, a recording medium sheet feeder 42, etc., are provided. Then, the control means 44 controls the rotation of the developing roller 30 in a mode different from that at the time of developing, while the sucking pump 39 is operated so as to remove the developing liquid from the face of the developing roller 30 after the development is finished, and controls the developing roller 30 so as to carry the recording medium sheet, remove the developing liquid from the surface of the recording medium sheet, and dry the recording surface of the sheet, as well. Thus, an exclusive developing liquid removing means is eliminated, the structure is simplified, and the miniaturization of the device is attained.
