  • Patent number: 8903286
    Abstract: Disclosed herein are an image forming apparatus and a control method thereof. In the image forming apparatus, an intermediate transfer member is provided with a position identification mark, to enable sensing of a position of the intermediate transfer member after a cleaning unit is completely spaced apart from the intermediate transfer member. An image formation/transfer position can be controlled in response to a sensing signal of the position identification mark, so that respective colors of developer images may be formed and transferred to the same position on the intermediate transfer member in a state in which contact between the cleaning unit and the intermediate transfer member is released. This minimizes and/or prevents color discrepancy between the respective colors of developer images.
