A conveying mechanism includes: a first belt roller; a second belt roller provided substantially parallel to the first belt roller downstream in the conveying direction of the recording medium; a conveying belt looped over at least the first belt roller and the second belt roller; a belt drive unit conveying the conveying belt; a resist roller pair configured by a first resist roller and a second resist roller contacting the first resist roller; and a resist roller drive unit driving the rotation of the first resist roller or the second resist roller. The first belt roller and the first resist roller are coaxially arranged, and the first belt roller rotates independent of the first resist roller.
