Abstract
A liquid application apparatus includes: an application member which applies a first liquid to a recording medium; and a liquid holding member which abuts against the application member so as to form a liquid holding space in which the first liquid is held in such a manner that the first liquid held in the liquid holding space is applied to the recording medium via the application member by rotating the application member, wherein a supply port for supplying the first liquid in the liquid holding space and a recovery port for recovering the first liquid from the liquid holding space are provided in the liquid holding member, and the supply port and the recovery port are located in different positions in terms of vertical direction.
Claims16
A liquid application apparatus comprising:
- an application member which applies a first liquid to a recording medium;
- and
- a liquid holding member which abuts against the application member so as to form a liquid holding space in which the first liquid is held in such a manner that the first liquid held in the liquid holding space is applied to the recording medium via the application member by rotating the application member, wherein
- a supply port for supplying the first liquid in the liquid holding space and a recovery port for recovering the first liquid from the liquid holding space are provided in the liquid holding member, and
- the supply port and the recovery port are located in different positions in terms of vertical direction.
A liquid application method using a liquid application apparatus,
- wherein the liquid application apparatus includes:
- an application member which applies a first liquid to a recording medium;
- a liquid holding member which abuts against the application member so as to form a liquid holding space in which the first liquid is held in such a manner that the first liquid held in the liquid holding space is applied to the recording medium via the application member by rotating the application member;
- a supply port which is provided in the liquid holding member and supplies the first liquid in the liquid holding space, and a first recovery port and a second recovery port which are provided in the liquid holding member and recover the first liquid from the liquid holding space, the first recovery port being located above the supply port in terms of vertical direction, the second recovery port being located below the supply port in terms of the vertical direction;
- a liquid storing device which stores the first liquid recovered from the liquid holding space;
- a first recovery flow channel connected to the first recovery port;
- a second recovery flow channel connected to the second recovery port;
- a third recovery flow channel connected to the liquid storing device;
- and
- a flow channel switching device which is connected to the first to third recovery flow channels and selectively switches between a state where the first recovery flow channel is connected to the third recovery flow channel and a state where the second recovery flow channel is connected to the third recovery flow channel,
- wherein the liquid application method comprising the step of applying the first liquid to the recording medium by the application member, and
- wherein, while the application member applies the first liquid to the recording medium, the flow channel switching device maintains the state where the first recovery flow channel is connected to the third recovery flow channel.
