<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that uses a direct transfer system and an indirect transfer system in combination, the apparatus being configured to improve position accuracy for alignment for all colors, and to provide an image forming method and a program. <P>SOLUTION: A velocity control unit 52b performs acceleration control or deceleration control on at least one of motors M1 and M2 to accelerate or decelerate at least one of the surface velocity V1 of an intermediate transfer belt 6 and the surface velocity V2 of a transfer-sheet conveying belt 8 to thereby match the phase of the fluctuation of the surface velocity V1 of the intermediate transfer belt 6 and the phase of the fluctuation of the surface velocity V2 of the transfer-sheet conveying belt 8. Hence it is possible to minimize a velocity difference between the intermediate transfer belt 6 and the transfer-sheet conveying belt 8 at a secondary transfer position B. As a result, in the image forming apparatus that uses the direct transfer system and the indirect transfer system in combination, it is possible to improve position accuracy for alignment for all colors. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
