Summary:A collection roller and a developing sleeve rotate in the same direction at proximal portions thereof. A distal end of a magnetic brush formed of developer born on a surface of the developing sleeve by an importing magnetic pole of a magnet roller is set so as to make contact with the surface of the collection roller. A first gap is set between the collection roller and the developer-bearing region of the developing sleeve and a second gap larger than the first gap is set between the collection roller and the non-developer-bearing region of the developing sleeve.
