Claim 17:
18. An image forming apparatus, comprising:
an image carrier that extends in a first direction;
a light emitter that includes:
a substrate that extends in the first direction; and
a plurality of light-emitting devices that are disposed on the substrate and emit light to the image carrier;

a positioning portion that is disposed between the substrate and the image carrier, and that fixes a position of the light emitter with respect to the image carrier in at least one direction perpendicular to a light emission direction of the light emitter, wherein the positioning portion is a protrusion; and
an adjuster that is located to overlap the positioning portion when viewed in the first direction, and that adjusts the position of the light emitter in the light emission direction, wherein the adjuster includes a driving source that moves the light emitter,
wherein the positioning portion includes:
a first positioning portion disposed at a first end portion in a direction in which the substrate extends, wherein the first positioning portion is a protrusion; and
a second positioning portion disposed at a second end portion in the direction in which the substrate extends, wherein the second positioning portion is a protrusion,

wherein while being restricted by a first restrictor included in the image carrier, the first positioning portion has a position fixed in a width direction of the substrate, the width direction being included in the at least one direction perpendicular to the light emission direction, wherein the first restrictor is a recess, and
wherein while being restricted by a second restrictor included in the image carrier, the second positioning portion has a position fixed in the width direction of the substrate and in the direction in which the substrate extends, the width direction and the direction in which the substrate extends being included in the at least one direction perpendicular to the light emission direction, wherein the second restrictor is a recess.
