PROBLEM TO BE SOLVED: To improve the specification efficiency of a transfer device by controlling the toner image formation in accordance with the number of sheets, the size, and the number of images. SOLUTION: The controller 100 is mainly constituted of a CPU 101, a ROM 102 for storing the control program of the CPU 101 and a RAM 103 as a work memory required for the CPU 101 to execute the control program. And a motor drive instruction signal S1, a developing device drive instruction signal S2 and a paper carrying drive instruction signal S3, etc., are generated from a mechanism control part 106 under the control of the CPU 1 in accordance with printing data generated by the controller 202. Besides, in a printing information deciding processing, the printing data from an information processor 200 is communicated with the controller 202, then, each timing of forming a latent image, developing, transferring, fixing and carrying the paper, etc., after that is controlled based on data on the printing size, the number of sheets, printing color, etc. Thus, a color toner image is efficiently used on the surface of a transfer drum, so that a printing speed is improved. |
