Abstract
Official abstract text for this publication.
An image forming apparatus includes an image forming unit that forms an image on a recording medium; a width detector that detects positions of side edges of the recording medium in a width direction, which is orthogonal to a conveying direction in which the recording medium is conveyed, at multiple detection positions along the conveying direction; a shape calculator that calculates angles between the conveying direction and straight lines each connecting the positions of the same side edge detected at the multiple detection positions and calculates a shape of the recording medium based on the angles; and a correction unit that corrects image data of the image to be formed by the image forming unit based on the calculated shape of the recording medium.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus, comprising: an image forming unit that forms an image on a recording medium; a width detector that detects positions of points on side edges of the recording medium in a width direction that is orthogonal to a conveying direction in which the recording medium is conveyed, wherein the width detector detects the positions of the points on the side edges of the recording medium at multiple detection positions along the conveying di…
