Abstract
An image forming apparatus includes a plurality of heads and a head support member. Each head has multiple nozzles arrayed in at least one row to eject liquid droplets. The support member has first and second positioning portions to position each head. Each head has a first positioning face to position each head in a nozzle array direction and a second positioning face to position each head in a direction perpendicular to the nozzle array direction. The first positioning face and the second positioning face are cut faces formed by cutting. Each of a first distance between the first positioning face and a first reference nozzle and a second distance between the second positioning face and a second reference nozzle is uniform between the heads. Each head is mounted to the support member with the first and second positioning faces contacting the first and second positioning portions, respectively.
