The linehead of an image forming apparatus includes a common ink chamber, a plurality of nozzles, an individual ink flow path, an ink supply path, a first piezoelectric actuator, and a second piezoelectric actuator. One end of the individual ink flow path is connected to the nozzle. The ink supply path is connected to the individual ink flow path and the common ink chamber. When putting the nozzle into a drying prevention state, the control unit deforms the first piezoelectric actuator in a direction in which a capacity of the individual ink flow path increases, to thereby draw an interface of ink to inside the nozzle. Further, the control unit deforms the second piezoelectric actuator, to thereby close the ink supply path.Type: ApplicationFiled: December 24, 2020Publication date: July 1, 2021Inventors: Kohei FURUKAWA, Shinichiro Yamada
