Abstract
PURPOSE: To improve developing and transfer characteristics and improve copying quality by so constituting the apparatus that the specific resistances of magnetic toners become larger than 1/10 the specific resistance of photoreceptor and less than 100 times that and come within a range of 1016Ωcm or under.
CONSTITUTION: When a photoreceptor 1 rotates in the arrow a direction and a magnet roll 5 rotates in the arrow b direction, the magnetic toner 8 being supplied from a magnetic toner replenishing vessel 9 moves in the arrow C direction and the magnetic toner 8' deposit on the latent image portions formed on the photoreceptor 1, whereby developing is accomplished. Here, arrangement is so made that the specific electric resistance values of the magnetic toners 8, 8' used become larger than 1/10 the specific electric resistance value in the dark resistance region of the photoreceptor 1 and less than 100 times that and come within a range of 1016Ωcm or under, whereby the developing characteristics and transfer characteristics may be improved and the distinct and good quality images obtained.
