摘要： An image forming apparatus and an auto color registration method thereof. The image forming apparatus performs an auto color registration (ACR) operation by excluding or minimizing the influence caused by variation in speed of a drive unit driving a transfer member. The image forming apparatus includes a controller, which prints a test pattern of each color according to a rotation period of the drive unit, and controls an operation for outputting an image in which each color registration error is corrected on the basis of the test pattern, such that a reliability of the ACR operation is increased and a quality of an image output from the image forming apparatus is also increased.

摘要： A transfer member to transfer a document at different transfer speeds according to transfer sections of a document transfer path includes a first transfer roller and a second transfer roller, both of which are respectively mounted at upstream and downstream sides of the document transfer path, and a driving unit to drive the first and second transfer rollers such that the speed of the second transfer roller is higher than that of the first transfer roller under the control of a control unit is further included. The control unit reads an image pattern on a test document using a read device, acquires speed compensation information to compensate for a transfer speed of the transfer member, and controls an operation of the transfer member according to the speed compensation information at the time of transferring the document.
