Abstract
A developing device is provided for developing by means of a toner an electrostatic latent image formed on the surface of a photosensitive drum which rotates along one direction at a given speed. The developing device comprises a developing roller movably disposed at a given distance from the photosensitive drum, for causing the toner thereon to move in accordance with the movement thereof, whereby the toner thereon is supplied to the photosensitive drum by means of the surface potential of the electrostatic latent image, and a layer regulating member for regulating the amount of the toner put on the developing roller. The developing roller rotates in other direction at a speed relative to the given speed.
