发明名称 LIQUID DISCHARGE HEAD UNIT AND IMAGE FORMING APPARATUS
摘要 A liquid discharge head unit includes a liquid container tank storing a liquid and a head discharging liquid droplets from its nozzles. The head includes a common channel supplying the liquid to liquid-chambers communicating with the nozzles, and the common channel includes a supply port introducing the liquid and a discharge port discharging the liquid. The liquid container tank includes a container including upstream and downstream chambers separated via a filtering member, a supply path supplying the liquid from the downstream chamber to the supply port of the head, a discharge path discharging the liquid obtained from the discharge port of the head, a communication path via which the downstream chamber communicates with the discharge path, and a communication path via which the upstream chamber communicates with the discharge path, where a fluid resistance of the second communication path is higher than that of the first communication path.
