ABSTRACT:
A copy sheet is held between a reciprocally rotatable drum and a holding roller which bears against the drum, and for each reciprocal rotation of the drum, an electrostatic latent image corresponding to one of a plurality of selected color separation images is formed on the sheet and each image is developed with a corresponding color developing solution. A mechanism is provided which is effective to prevent misalignment, in particular, lateral misalignment, between the plurality of color separation images which are formed in superposed manner on the sheet. After the formation of the electrostatic latent image, the sheet on the drum has its free end moved away from the peripheral surface thereof and is delivered, in floating condition, into a vessel which contains a corresponding color developing solution for the purposes of developing. This manner of developing minimizes the attachment of color developing solutions to unwanted portions and to prevent a mixing of different color developing solutions.
