Abstract

Provided is a double-side printing apparatus, which comprises a printing unit capable of forming an image on a paper sheet of a paper width (Lp) with a paper gap (Lg) and at a printing transfer velocity (Vg), an equal-velocity transfer unit for transferring the paper sheet at the printing transfer velocity (Vg) from a resist unit through the printing unit to a velocity-changing position, a variable-velocity transfer unit for transferring the paper sheet from the velocity-changing position to the resist unit, and a transfer control unit for controlling the paper sheet transferring velocity. The section for the variable-velocity transfer unit to transfer the paper sheet includes an acceleration/deceleration section for inverting the paper sheet in a paper sheet inverting passage, and an equal-velocity section, for which the paper sheet is transferred at an equal transfer velocity (Vr). The transfer control unit sets a circulation number (N), and calculates the transfer velocity (Vr) by using the acceleration, the paper width (Lp), the paper gap (Lg) and the printing transfer velocity (Vg) so that the paper sheet may be circulated and transferred at N x (Lp + Lg)/Vg.
