Patent ID: 8335446

Claim:
An image forming apparatus comprising: a direct-transfer control unit that causes a single-color-image forming unit and a direct transfer member to transfer an image formed by the single-color-image forming unit onto any one of the direct transfer member and transfer paper conveyed by the direct transfer member; an indirect-transfer control unit that causes a multiple-color-image forming unit and an intermediate transfer member to superimpose different color images formed by the multiple-color-image forming unit onto the intermediate transfer member; a first detecting unit that detects first information relevant to conveyance velocity of the intermediate transfer member; a second detecting unit that detects second information relevant to conveyance velocity of the direct transfer member; and a print control unit that causes at least any one of the direct-transfer control unit and the indirect-transfer control unit based on the first information detected by the first detecting unit and the second information detected by the second detecting unit to make the conveyance velocity of the intermediate transfer member and the conveyance velocity of the direct transfer member equal to each other.
