Abstract

PURPOSE: To enhance developing efficiency and enable copied images of good quality to be obtained by making the developer conveying surface of a developing roll insulation type and making the developer conveying surface of a developer feed roll conductive.
CONSTITUTION: A developing roll 7 is provided in opposition to a photoreceptor 5 and a developer feed roll 6 is disposed thereunder in opposition to a developing roll 7. This developing roll 7 and developer feed roll 6 are constituted respectively by magnet rolls 2', 2 and cylindrical non-magnetic material sleeves 1', 1 which enclose these and are supported reciprically rotatably with respect to these. The surface of the non-magnetic material sleeve 1' of the developing roll 7 is formed with insulation-type covering and the non-magnetic material sleeve 1 of the developer feed roll 6 is formed by conductor. Such constitution enables developing efficiency to be enhanced and the copy images of good quality to be obtained.
