Abstract

PURPOSE:To realize the simple constitution of a bicolor developing device which does not require high accuracy by swinging two oscillatory developing devices through a cam member and putting them opposite an image carrier selectively. CONSTITUTION:A shaft 12 is rotated at a reduced speed by a series motor M, a worm W, a worm gear GIA, a gear GIB, a stepped gear G2, etc., which are started and stopped under the control of a light shield plate 18 and a photosensor unit 19, and the cam member 13 united with the shaft 12 also rotates. Then the member 13 presses a pressure plate 14A or 14B and a rotatable developing device 10 swings around a shaft 10C as a fulcrum with the reaction of a spring 15A or 15B. Consequently, the developing sleeve 111A or 111B of the developing device 11A or 11B faces a photosensitive drum 2 and a latent image on the drum 2 is developed by the bicolor developing device of simple constitution which does not require high accuracy.
