摘要：
A device for detecting image information includes an intermediate transfer member configured to hold a pattern image; a detecting unit configured to optically detect the pattern image; a secondary transfer unit configured to contact with and separate from the intermediate transfer member; and a control unit that controls the secondary transfer unit in such a manner that the secondary transfer unit does not contact the intermediate transfer member while the detecting unit is detecting the pattern image, and that controls the secondary transfer unit in such a manner that the secondary transfer unit contacts the intermediate transfer member after the detecting unit finishes detection of the pattern image.
