A belt driving control apparatus which realizes high-precision belt driving by specifying with high precision the pitch line distance (PLD) or thickness that affects the belt movement speed. This belt driving control apparatus controls the driving of the belt (103) by controlling the rotation of driving supporting rotating bodies (105) via which the rotational driving force is transmitted, among the plurality of supporting rotating bodies on which the belt is installed. This control apparatus controls the rotation of the driving supporting rotating bodies on the basis of rotation information relating to the rotational angular displacement or rotational angular speed in two supporting rotating bodies among the plurality of supporting rotating bodies which have different diameters, or the different degree to which the PLD of the portion of the belt that is wound on each of these supporting rotating bodies affects the relationship between the movement speed of the belt and the rotational angular speed of each of these supporting rotating bodies, so that the fluctuation in the movement speed of the belt that is generated by the fluctuation in the PLD along the circumferential direction of the belt is reduced. <IMAGE> |
