Abstract

An image formation device, which includes: an exposure head in which a screw having an axis directed to a focus direction for a photoreceptor is fixed in the vicinity of each side of the exposure head; a housing to which the exposure head is attached; a nut attached to the screw; a fixing member that limits movement of the nut with respect to the housing; and an elastic member that elastically supports the exposure head against the housing in the vicinity of the screw in the focus direction for the photoreceptor and a sub-scanning direction, in which the exposure head is moved, by rotation of the nut, in the focus direction against an elastic force by the elastic member, and a position of the exposure head with respect to the photoreceptor is adjustable in the focus direction.
