Claim 0:
1. 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, wherein the plurality of light-emitting devices are staggered when viewed in a direction perpendicular to the first direction;

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;
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, and the adjuster includes a contact member that comes into contact with the substrate to move the substrate in the light emission direction; and
a support member attached to an apparatus body to rotatably support the image carrier, wherein the support member is a flange,
wherein the positioning portion protrudes from the substrate toward the support member and is fitted to a recess formed in the support member.
