PROBLEM TO BE SOLVED: To provide a sheet conveyance device capable of compensating skewing of a sheet and horizontal registration with high precision irrespective of width of the sheet. SOLUTION: A nipping and holding position for the sheet P is set in accordance with width of the sheet P. If pressurizing rollers at the set nipping and holding position are pressurizing rollers 201e, 202e, each of the pressurizing rollers 201e, 202e is abutted on corresponding conveyance rollers 201b, 202b, respectively. A driving profile is calculated in accordance with the attitude of the sheet P detected by a sheet sensor 204, and each of pulse motors 201, 202 drives conveyance rollers 201a to 201c, 202a to 202c in accordance with the calculated driving profile. Consequently, skewing of the sheet P and horizontal registration are compensated during conveyance of the sheet P, and its attitude (the attitude shown by the solid line in the drawing) is returned to normal attitude (the attitude shown by the dotted line).
