Abstract
A head module includes a liquid discharge head, a liquid storage, and a heater. The liquid discharge head discharges a liquid in a first direction. The liquid storage stores the liquid. The liquid storage includes a first wall, a second wall opposite the first wall in a second direction intersecting the first direction, an inlet on one end of the liquid storage, an outlet on another end of the liquid storage, and multiple partitions. The inlet introduces the liquid to the liquid storage. The outlet feeds the liquid to the liquid discharge head. The multiple partitions extend from the first wall toward the second wall with gaps between tips of the multiple partitions and the second wall in the second direction, respectively. The multiple partitions are arranged at intervals in the first direction. The heater is disposed on the first wall to heat the liquid in the liquid storage.
