PURPOSE:To prevent the dislocation of a formed image by storing the pattern of changes in the angular velocity of a transfer roll beforehand and controlling the angular velocity of the rotation of a driving motor driving the transfer roll based on the pattern of the changes. CONSTITUTION:The memory means stores beforehand the information of the changes in the angular velocity of the transfer roll 1 when the driving motor 5 driving the transfer roll 1 is rotated at a specified angle. When transfer is performed, the information of the changes in the angular velocity is read from the memory means and the angular velocity of the driving motor 5 is changed based on the information. Thus, the angular velocity of the transfer roll 1 is fixed and the dislocation of the image can be prevented when multiplex transfer is performed. |
