Abstract
An electrophotographic recording apparatus having a photoconductive element, means for providing an electrostatic latent image on the photoconductive element which corresponds to image light, a developing device for developing the latent image to produce a visible image, means for transferring the visible image onto a paper, and means for cleaning the surface of the photoconductive element after the transfer of the visible image. Developers of different colors are selectively supplied to the single developing device to selectively record images in different colors. When a predetermined period of time has expired with no recording action taken after the completion of color recording, a developer collection system is communicated to a cleaning liquid vessel. This shortens the period of time necessary for the next change of recording color and recording operation while allowing a minimum of damage to result from a trouble in the developer collection system.
