Abstract

PURPOSE:To clearlypeel and mix magnetic toner on a development sleeve excellently, by providing a magnetic wire, 0.1-2mm. in diameter at the upper stream than a toner layer thickness restricting member by 3mm.. CONSTITUTION:A development sleeve 2 is rotatably provided to a photoreceptor drum 1 with a suitable minute interval. A doctor member 7 restricting the thickness of development agent layer is fixed to a development housing at the opposite side to the photoreceptor drum of the development sleeve, and a peeling member 9 is provided at the upper stream side. A part opposing to the sleeve of the seeling member is bonded with a magnetic wire 11 made of piano wire, 0.1-2mm. in diameter at the tip of a non-magnetic regid plate 10 having a plurality of ribs of comb shape. A distance l between the magnetic wire and the doctor member has a suitable range depending on the wire size, and if the diameter is 3mm. or more, excellent peeling and mixture and made independently of the size of diameter.
