A printer includes a recording unit, a glue belt, a pressing roller, a blowing unit, an ion application unit, and a charging unit. The glue belt includes an outer peripheral surface configured to support a medium. The pressing roller is provided upstream of the recording unit in a circumferential direction, and presses the medium against the outer peripheral surface. The blowing unit is provided upstream of the recording unit and downstream of the pressing roller in the circumferential direction and configured to blow a gas toward the outer peripheral surface. The ion application unit applies ions having a positive polarity to the gas blown onto the outer peripheral surface. The charging unit charges a front surface configured to come into contact with the medium so that the polarity of the potential of the front surface is the same as the polarity of the ions applied to the gas.

An ink tank unit includes: an ink tank that is able to contain ink; an ink filling unit that is provided in a case of the ink tank and has an opening which enables the ink tank to be filled with the ink; and a second case that covers at least a part of a peripheral section of the ink filling unit, of a fifth wall of the case on which the ink filling unit is provided. A recessed section and a side wall which enables the ink to be guided to the recessed section are provided on at least one section of the peripheral section of the fifth wall and a section of the second case, which faces the peripheral section.

A liquid container includes an ink chamber containing an ink to be supplied via a tube to a liquid ejecting head consuming the ink; an outlet port from which the ink contained in the ink chamber flows to the tube side; an injection port through which the ink can be injected into the ink chamber; and an air intake port taking air into the ink chamber from a further vertically upper position than a liquid level of the ink when the ink is contained in the ink chamber. If the ink equal to 5% of containing capacity containable in the ink chamber flows from the outlet port, the liquid container has an area where a fluctuation range of the liquid level of the ink inside the ink chamber becomes 5% or less of the cubic root of the containing capacity.
