According to this invention, a first encoder detects a conveyance amount by a first conveyance roller, provided in a conveyance path, for conveying a printing medium. A second encoder detects a conveyance amount by a second conveyance roller provided in the conveyance path in the conveyance direction of the printing medium at the downstream side of the first conveyance roller for conveying the printing medium. On the other hand, a signal output from the first or second encoder is selected on the basis of the position of the printing medium on the conveyance path.
