Abstract
A developing apparatus which includes a developing sleeve rotatably provided to confront an object to be developed, a magnet roller incorporated within the developing sleeve so as to be driven for rotation in the same direction as the developing sleeve, and a supply device for supplying developing material onto the peripheral surface of the developing sleeve. The developing apparatus is so arranged as to satisfy such conditions as EQU D.multidot..pi..multidot.Wsl>d1.multidot.p.multidot.Wmg where PA0 D: developing sleeve diameter (mm) PA0 Wsl: developing sleeve revolutions (rpm) PA0 d1: the closest distance between the sleeve surface and the object to be developed PA0 p: number of poles of the magnet roller PA0 Wmg: revolutions of the magnet roller (rpm).
