PROBLEM TO BE SOLVED: To improve printing quality of a liquid injection device.SOLUTION: A liquid injection device comprises: a print head 66; a liquid supply unit capable of supplying liquid containing pigment to the print head 66. A reservoir 273 communicating with a plurality of nozzles 267 constituting a nozzle array 268 extending in a first direction and a reception port 279 capable of introducing the liquid to the reservoir 273 are formed to the print head 66. When the print head 66 is viewed in a plan view, a nozzle positioned at one end in the first direction out of the plurality of nozzles 267 is defined as a first nozzle 267A, and a nozzle positioned at the other end is defined as a second nozzle 267B. A first portion 301 being one end portion in the first direction out of an outer circumference of the reception port 279 is closer to the first nozzle 267A than a second portion 305. The liquid supply unit can supply second liquid 339 out of first liquid 338 containing the pigment and the second liquid 339 having a low content of the pigment than that of the first liquid 338 to the first portion 301 of the reception port 279.SELECTED DRAWING: Figure 33 |
