Abstract

PURPOSE: To evacuate the head interior to a negative pressure by means of developer suction pump, facilitate supply of liquid, and reduce the size of head, by minimizing the spacing between the developing head and photoreceptor, and providing seal members on the both ends of the head.
CONSTITUTION: A feed port 3 communicating with a liquid feed pipe 4 and a suction port communicating with a liquid suction pipe 6 are provided in a developing head 2, and this liquid suction pipe 6 is connected to a suction pump P. The developing head 2 is disposed closely to the surface of the photoreceptor so that the interior thereof may be maintained at a negative pressure by the suction pump P to such an extent as to enable supply of developer through the liquid feed pipe 4, and seal members 7 are provided on both ends of the head 2. As a result, the supply of developer may be smooth, and stable supply may be realized, so that high quality images may be formed. At the same time, the developing head may be reduced in size.
