Abstract:
1. A liquid coating apparatus comprising: a coating roller which has a coating surface applying a liquid onto a sheet-form medium; a liquid holding unit which abuts against the coating surface of the coating roller so as to form a liquid holding space from which the liquid is fed to the coating surface; a medium support member which faces the coating surface of the coating roller across the medium in such a manner that the medium support member and the coating roller nip and support the medium; an abutment pressure-varying device which adjusts an abutment pressure exerted between the coating surface of the coating roller and the liquid holding unit; and a control device which is configured to control the abutment pressure-varying device according to a relative position of the medium with respect to the coating roller so as to adjust the abutment pressure in such a manner that: the abutment pressure is set to a first pressure value P wherein the coating roller rotates while the medium is sandwiched by the medium support member and the coating roller in such a manner that the liquid is fed to the coating surface from the liquid holding unit and the liquid is transferred to the medium from the coating surface.
