ABSTRACT:
A liquid droplet ejection apparatus comprising: a conveyor portion that conveys a recording medium to a liquid droplet ejection region by the rotational force of a drive roll; liquid droplet ejection heads that eject liquid droplets onto the recording medium conveyed to the liquid droplet ejection region by the conveyor portion; a feed portion that feeds the recording medium to the conveyor portion at a predetermined feed timing; a detection portion that detects a rotational position of the drive roll; and a control portion that controls the feed timing of the feed portion based on the rotational position that the detection portion has detected, so that when the drive roll reaches a predetermined rotational position, the control portion causes the recording medium to be conveyed to the liquid droplet ejection region and causes the liquid droplet ejection heads to start ejecting the liquid droplets onto the recording medium, is provided.
