Abstract
Official abstract text for this publication.
An image forming apparatus contains a registration correction portion correcting an inclination of the sheet of paper by hitting a forward end of the sheet of paper against a pair of registration rollers, a detection portion that detects an amount of deviation in the sheet of paper, a control portion that calculates a command value of movement for correcting the amount of deviation and a moving portion that moves the registration rollers toward a direction which is perpendicular to a sheet-conveying direction based on the command value of movement with the sheet of paper being nipped with the registration rollers. The control portion controls the moving portion so that the movement of the registration rollers finishes before a limited time of movement or below an upper limit of movement set in relation to the command value of movement.
First claim
