Abstract
An image processing apparatus includes a reading part configured to optically read skew amount measurement patterns and opposite ends of a paper sheet; an image skew amount detecting part configured to detect skew amounts on a color basis based on the skew amount measurement patterns; a paper sheet skew amount detecting part configured to detect a skew amount of the paper sheet based on a displacement between the opposite ends of the paper sheet; a skew correction amount calculating part configured to calculate skew correction amounts of the respective colors based on the skew amounts; and a skew correcting part configured to shift the images to correct the skews by recording input image data in plural lines of a line memory, dividing the input image data into plural areas in a main scanning direction, and setting line delay amounts on an area basis based on the skew correction amounts.
