Abstract

PURPOSE:To prevent minute powder toner from being sticked on the developing sleeve, by returning residual toner with a cleaning sleeve provided with a rotating multi-magnetic pole magnet roller at the inside to a supply section. CONSTITUTION:A residual toner layer 51' on a developing sleeve 1 returning to a toner hopper 3 after passing through a development section A produces 51'' after being transferred on a cleaning sleeve 7 in peeling-off manner from a developing sleeve 1 with a magnetic field of a magnet roll 8 at a position (A) by a little this side to the most closing part with a cleaning sleeve 7. The transferred toner 51'' is carried by almost one circle in the path of the lower surface, right side surface and upper surface, while being stored on the circumference of the sleeve 7 at a rotating magnetic field by a clockwise rotation b of the magnet roll 8. On the development sleeve 1 removed with a residual toner, the thin layer of the toner 5 in the hopper can be formed and held at a magnetic blade 4.
