PURPOSE:To execute the synthesis mode at a low cost by forming a picture at a prescribed position in an area of an image carrier corresponding to designated transfer paper every time an original picture is received so as to omit a picture memory. CONSTITUTION:Reading of Bk picture data is started by a color scanner when copying is started and optical write and latent image forming are started based on the picture data. Before a latent image tip reaches a development position of a Bk developer 14 so as to develop the tip of a Bk latent image, the rotation of a development sleeve 14-1 is started to execute agent napping thereby developing the Bk latent image by a Bk toner. When the end passes through the development position after the latent image forming, the agent of the sleeve 14-1 is quickly interrupted. The Bk toner image formed on a photosensing drum is transferred to the surface of an intermediate transfer belt 19 rotated at an equal speed to that of the photosensing drum. Toner images of Bk, C, M, Y formed sequentially on the photosensing body drum are positioned sequentially to a belt 19 to form a belt transfer picture in four color overlapping and the picture is transferred onto the transfer paper simultaneously. |
