Abstract

PURPOSE:To prevent clogging of the toner in the opening part of a hopper by providing a bottom plate in such a position where the toner moves on a developing roller along the same within a range that it receives the influence of magnetic fields and is conveyed upward above the horizontal plane of the roll. CONSTITUTION:A toner supply rate regulating member 7 serving also as a bottom plate for a toner hopper 2 to be installed above a developing roll is provided in such a manner that the toner in the hopper moves along the roll within a range where it receives the influence of the magnetic field of the roll and the opening part of the hopper is located above the horizontal plane HH' past the center of the roll and so as to come to the position where the toner is conveyed from below to above. Thereby, the occurrence of blocking of the toner in the hopper and its clogging in the opening part is obviated, and further the occurrence of toner clad in the toner stagnating part is prevented.
