An apparatus for electrostatic latent image development having two or more units for multicolor development provided around a photoreceptor. Each unit has a developer feed controller for feeding developer to the developing section having a developing roller facing the photoreceptor drum and for shutting off the feeding and has a doctor blade in the feed up-stream in turning direction of the developing roller. Developer is applied to the developing section when development is performed by displacement of the developer feed controller and is shut off when the developing unit is not used for development.
