Abstract
An image forming apparatus includes: an image holder; an exposure member that has an exposure portion exposing the image holder; a first positioning unit that determines a distance in a first direction, which is a direction of an optical axis of the exposure member, between the exposure member and the image holder; and a second positioning unit that determines a position of the exposure member with respect to the image holder in a second direction being a direction of an axis line of the image holder, and a position of the exposure member with respect to the image holder in a third direction being perpendicular to both the first direction and the second direction, and that determines the distance between the exposure member and the image holder at a position substantially closer to the exposure member than the position of the first positioning unit.
