Abstract
There is provided a new image formation apparatus which does not generate a positional gap or discrepancy of a transferred image even when a final product is dependent upon a manufacturing accuracy in the exposure portion, particularly at the time of formation of the color image. Further, the present invention provides a new image exposure apparatus such as an LED head, an EL head, an LD scan unit, etc. which are used for the image formation apparatus. The image formation apparatus comprises an image storage device for storing image information, a read-out device for assigning an image information read-out position of an image storage device to read out the image information, an image transfer unit for transferring an image onto a paper in accordance with the image information read out by the read-out device from the image storage device, and an accuracy information storage device for storing position accuracy information in a scanning direction of the image transfer unit. The read-out device has a device for reading out the position accuracy information from the accuracy information storage device and correcting the image information read-out position by the position accuracy information.
