Patent ID: 8320804

Claim:
An image forming apparatus, comprising: a toner image carrying member that moves while carrying a toner image, the toner image being formed by each of a plurality of image forming units respectively forming color toner images; a first transferring member that is arranged for each of the plurality of image forming units and that sequentially transfers, onto the toner image carrying member, the toner image formed by each of the plurality of image forming units; a second transferring member that transfers, on a recording medium, the toner image that the toner image carrying member carries; a transporting unit that transports the recording medium along a transport path that passes through a transfer region where the second transferring member transfers the toner image onto the recording medium; a controller that controls a movement speed of the toner image carrying member; and a memory that stores a control profile, the control profile defining a relation between a position of the recording medium on the transport path and the movement speed of the toner image carrying member to be set according to the position of the recording medium, wherein the controller acquires the control profile from the memory and information on timing when the transporting unit starts transporting the recording medium, and in response to the acquired information, changes the movement speed of the toner image carrying member according to the control profile, thereby controlling and setting the movement speed of the toner image carrying member at the time of transfer by the first transferring member so as to cancel out changes in the movement speed of the toner image carrying member, the changes in the movement speed occurring according to a positional relationship between each of a leading end portion and a trailing end portion of the recording medium in the transporting unit, and a nip portion of the second transferring member.
