Abstract

PURPOSE:To enable high density image to be formed at high speed, by arranging at given clearances to a photoreceptor a couple of developing rollers one of which is used for a squeezing roller, too, and holding a developing fluid between both rollers. CONSTITUTION:Developing fluid 5 is drawn up with the first developing roller 6 and held between roller 6 and the second developing roller 7, both rotating in the direction reverse to photosensitive drum. Fluid 5 lengthens substantially developing time and roller 7 combines a squeezing roller, and further extends the developing time. Arranging clearance l1 between drum 1 and rollers 6, and clearance l2 between drum 1 and roller 7 so that l1>l2 permits developing speed inversely proportional to opposite electrode distance corresponding to clearances l1, l2 to be further raised and high density image to be formed at high speed. Similar results are obtained when roller 7 is rotated reversely to roller 6.
