Title:
IMAGE FORMATION DEVICE AND CURVE CORRECTION METHOD
Document Type and Number:
Japanese Patent JP2020014034
Kind Code:
A
Abstract:
To provide an image formation device and a curve correction method capable of improving picture quality, by suppressing deterioration of image location accuracy or image defect.SOLUTION: An image formation device includes: a resist roller 43 for transporting a sheet toward an image formation part 20; a first detector (a curve sensor 45) placed on farther upstream side than the resist roller 43 in the transport direction, and detecting a tip of the sheet; a first calculation part (a control section 11) for calculating a first curve amount of the sheet on the basis of the detection results by the first detector; a correction part (the control section 11) for correcting the curve of the sheet on the basis of the calculated first curve amount; a second detector (a bias sensor 46) placed on the farther downstream side than the resist roller 43 in the transport direction, and detecting a position of the sheet at one end in the width direction; a second calculation part (the control section 11) for calculating a second curve amount of the sheet on the basis of the detection results by the second detector; and an adjustment part (the control section 11) for adjusting a correction amount by the correction part on the basis of the calculated second curve amount.SELECTED DRAWING: Figure 2
