IMAGE FORMATION DEVICE AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a device or a method for correcting bending of paper by reflecting a correction control value of the bending of the paper of a simple-structured aligning device based on a detected stiffness strength of the paper accurately and without taking much time.

SOLUTION: Torque is adjust by an appropriate motor drive current of a loop roller with respect to the stiffness strength of the paper, and bending correction of the paper is performed by forming a loop at the upstream side of a registration roller without slipping of the paper and overloading the motor.
