摘要： In an image forming apparatus, a control device recognizes expansion and contraction of a pattern image based on an output of an image detector. The control device calculates a driving motor velocity fluctuation cancellation pattern for driving a common drive source. The driving motor velocity fluctuation cancellation pattern creates a latent image expansion and contraction cancellation pattern capable of canceling the expansion and contraction of the pattern image detected by the image detecting device. A process of obtaining the cancellation patterns is executed except when a print job for forming the toner image is executed in accordance with image information. The control device controls the common drive source in accordance with the cancellation driving motor pattern.

摘要： A belt driving controller is disclosed. The belt driving controller controls driving of a belt that is wound around plural sustaining rollers by controlling a driving sustaining roller that transmits a driving force to the belt. In two sustaining rollers, a calculating method for recognizing a PLD (pitch line distance) of the belt is used. In the calculating method, the delay period during which the belt moves a distance from a driven sustaining roller having a large diameter to a driven sustaining roller having a small diameter is determined to be shorter than before in the belt moving direction.

摘要： A belt drive control unit controls a rotation of belt supported by first and second rollers. Each of rotations of the first and second rollers are detected as first and second results. A rotation of the first roller is controlled in connection with thickness fluctuation in the belt using the first and second results. The belt drive control unit includes a sampling data acquisition unit, a correction value generator, a correction value storage, and a correction value reading controller. The sampling data acquisition unit obtains sampling data by sampling a difference value between the first and second results. The correction value generator generates correction value data for the belt based on the sampling data. The correction value storage stores the correction value data. The correction value reading controller reads the correction value data based on a rotation number of the belt to control a rotation of the first roller.

摘要： A belt driving control apparatus which realizes high-precision belt driving by specifying with high precision the pitch line distance (PLD) that affects the belt movement speed. This belt driving control apparatus controls the driving of the belt by controlling the rotation of driving supporting rotating bodies 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 in which the 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 is different, so that the fluctuation in the movement speed of the belt that is generated by the fluctuation in the PLD in the circumferential direction of the belt is reduced.
