ABSTRACT:
A multicolor developing device having a plurality of developing units interposed between a pair of rotary plates and disposed radially equidistantly relative to the axis of the rotation of the rotary plates, said each developing unit having a magnetic roller rotatably supported by a non-magnetic sleeve for carrying magnetic developing particles along the outer periphery of the non-magnetic sleeve by means of the magnetic forces developed by the magnetic roller so as to cause the particles to adhere to an electrostatic latent image to thereby develop the same into a visible image, and wherein the rotation of the rotary plates causes any one of developing units to register in facing relation with the electrostatic latent image.
