Abstract:
1. An image formation device comprising: an image-holding member that an image is formed thereon; an exposure section, that includes a plurality of light-emitting portions arranged in a first direction; a movement section, that moves the exposure section and the image-holding member relative to one another in a second direction, that intersects the first direction; and a light-emission control section which causes the plurality of light-emitting portions of the exposure section to periodically emit light in accordance with image data, which represents the image that is to be formed on the image-holding member, and causes the image to be formed on the image-holding member, the light-emission control section altering a light-emission period of the plurality of light-emitting portions during formation of the image so as to correct periodic variations in the image of at least one of density and magnification ratio along the second direction, the periodic variations corresponding with changes in a peripheral velocity of the image-holding member, the changes in the peripheral velocity repeating with a frequency equal to a frequency of the image-holding member.
