Abstract
A sheet detecting device includes a follow roller, an urging member, first and second support members, and a detecting unit. The second support member rotatably supports the follow roller and supports the urging member. The second support member is supported on the first support member, allowing the second support member to move to a first position when the drive roller and the follow roller nippingly convey the recording medium, and allowing the second support member to move to a second position upstream of the first position in the conveying direction when the recording medium is separated from the drive roller and the follow roller. The second support member is provided with a detection member that moves with the second support member when the second support member moves between the first position and the second position. The detecting unit detects the detection member, thereby detecting the position of the recording medium.
