Abstract

PURPOSE:To prevent a developing mark and whitening caused by the fact that a control member is clogged by a coagulating toner, paper powder, etc., by providing two stages or more of control members for thickness of a developer. CONSTITUTION:Thickness of a layer of a magnetic toner is controlled by providing a doctor blade 5 on the nonmagnetic developing sleeve 2. The tip of this doctor blade 5 is split, for instance, into two stages of edge parts 5', 5''. According to this constitution, even in case when a coagulating toner adheres to the doctor blade 5', and as a result, the space between the doctor blade 5' and the sleeve 2 has become unequal, since the tip 5'' is not under so large a load as 5' by a toner in the hopper, the space between the blade 5'' and the sleeve 2 can be kept equal, the toner is recoated by the blade 5'' and magnetic force made by the opposed magnetic pole. In this case, it is desirable that the lower flow side space l2 is made larger than the upper flow side space l2.
