A head cleaning device includes: a cleaning liquid holding unit provided with a cleaning liquid holding surface inclined corresponding to the nozzle surface of an ink jet head obliquely disposed; movement unit moving a head with respect to the cleaning liquid holding unit; and a cleaning liquid supply unit that supplies cleaning liquid from the upper portion of inclination so as to slide down the inclination of a cleaning liquid holding surface while cleaning liquid forms a meniscus between the cleaning liquid holding surface and the nozzle surface, in a state where the cleaning liquid holding surface and the nozzle surface face each other, and includes cleaning liquid nozzles disposed so that a position of the outer edge on the downstream side of the head in a movement direction is located further to the upstream side than the center in a head movement direction of the cleaning liquid holding surface.
