Patent ID: 7828411

Claim:
A liquid ejection apparatus, comprising: a print unit including a first ejection head which ejects a first liquid and a second ejection head which ejects a second liquid, the second ejection head being disposed on an upstream side of the first ejection head in terms of a first conveyance direction; a conveyance device which conveys a recording medium relatively with respect to the print unit; and a switch-back unit which reverses a relative conveyance direction of the recording medium, from the first conveyance direction in which the recording medium is relatively conveyed for a first time, to a second conveyance direction which is opposite to the first conveyance direction and in which the recording medium is relatively conveyed for a second time, wherein: the first ejection head ejects the first liquid toward the recording medium and the second ejection head does not eject the second liquid when the recording medium is relatively conveyed in the first conveyance direction for the first time; the switch-back unit reverses the relative conveyance direction of the recording medium from the first conveyance direction to the second conveyance direction; and the first ejection head does not eject the first liquid and the second ejection head ejects the second liquid toward the recording medium when the recording medium is relatively conveyed in the second conveyance direction for the second time.
