Driving method and liquid discharge apparatus

A liquid discharge apparatus comprising:

• a rotation mechanism that is configured to rotate a recording medium having a cylindrical shape;
• a liquid discharge head that is configured to form an image on a side surface of the recording medium, the liquid discharge head including a plurality of nozzle rows having a plurality of nozzles for discharging a liquid;
• and
• a control section that is configured to control the rotation mechanism and the liquid discharge head, wherein
• each of the plurality of nozzle rows has a plurality of nozzles arranged along a first axis,
• the plurality of nozzle rows are arranged in parallel,
• the rotation mechanism rotates the recording medium about a central axis of the cylindrical shape of the recording medium as a rotation axis in a state where the central axis is parallel to the first axis,
• the control section performs control to discharge the liquid from a part of the plurality of nozzle rows when an operation mode in which a nozzle row used to form the image among the plurality of nozzle rows is changed is a first mode,
• the control section performs control to discharge the liquid from the part of the plurality of nozzle rows and the other nozzle rows different from the part of the plurality of nozzle rows when the operation mode is a second mode different from the first mode, and
• a gap from an opening end of the nozzle in the part of the plurality of nozzle rows to the recording medium is narrower than a gap from an opening end of the nozzle in the other nozzle rows to the recording medium.
