Abstract
The reading apparatus is provided with: an optical image forming unit that forms an optical image on a recording medium by irradiating, with light, the recording medium on which an image is formed and which is transported in a slow scan direction; a reading unit that reads a position in a fast scan direction of the image formed on the recording medium transported in the slow scan direction and a position in a fast scan direction of the optical image, by using a minification optical system; and a registration correction unit that corrects a registration error in the fast scan direction of the image read by the reading unit, by using the position in the fast scan direction of the optical image read by the reading unit.
