An image formation device has an image formation section, a pattern image detection section and a registration correction section. The image formation section forms an image to be outputted and a pattern image on an image-bearing body, the pattern image is formed at a non-image creation region outside an image creation region at which the outputted image is formed. The pattern image detection section detects a position of the pattern image for detecting positional offset of the image. The registration correction section corrects the positional offset based on the detected position of the pattern image.
