HEAD MODULE, IMAGE FORMING APPARATUS, AND LIQUID DISCHARGE APPARATUS

Ahead module (20) includes at least two liquid discharge heads (21A, 21B), a reservoir (24), a heater (26), an inlet (50), a first outlet (51A), a second outlet (51B), and a wall member (27). The liquid discharge heads (21A, 21B) discharge liquid. The reservoir (24) stores the liquid. The heater (26) heats the liquid in the reservoir. The liquid is to be introduced from the inlet into the reservoir. The liquid in the reservoir is to be delivered from the first outlet to one (21A) of the liquid discharge heads. The liquid in the reservoir is to be delivered from the second outlet to another (21B) of the liquid discharge heads. A distance between the inlet and the first outlet (51A) is shorter than a distance between the inlet and the second outlet (51B). The wall member (27) is interposed between the inlet (50) and the first outlet (5 1A).
