Image forming apparatus and liquid removal capability setting method

An image forming apparatus, comprising:

• an ejection head which ejects liquid onto a recording medium to form a desired image on the recording medium;
• a conveyance device which moves at least one of the recording medium and the ejection head so as to move the recording medium in a conveyance direction relatively to the ejection head;
• a liquid removal device which performs liquid removal to remove the liquid on the recording medium and is arranged on a downstream side of the ejection head in the conveyance direction;
• a determination device which determines a state of the liquid removal device at least after the liquid removal is performed by the liquid removal device;
• and
• a liquid removal control device which implements control to adjust a liquid removal capability of the liquid removal device according to determination results of the determination device.

An image forming apparatus, comprising:

• an ejection head which ejects liquid onto a recording medium to form a desired image on the recording medium;
• a conveyance device which moves at least one of the recording medium and the ejection head so as to move the recording medium in a conveyance direction relatively to the ejection head;
• a first density determination device which determines density of the image formed on the recording medium and is arranged on a downstream side of the ejection head in the conveyance direction;
• a liquid removal device which performs liquid removal to remove the liquid on the recording medium and is arranged on a downstream side of the first density determination device in the conveyance direction;
• a second density determination device which determines the density of the image from which a portion of the liquid has been removed by the liquid removal device, the second density determination device being arranged on a downstream side of the liquid removal device in the conveyance direction;
• and
• a liquid removal control device which implements control to adjust a liquid removal capability of the liquid removal device according to determination results of the first density determination device and the second density determination device.

A liquid removal capability setting method, comprising:

• an image formation step of ejecting liquid onto a recording medium to form a desired image on the recording medium;
• a liquid removal step of removing the liquid on the recording medium by means of a liquid removal device, after the image formation step;
• a state determination step of determining a state after the liquid removal step;
• and
• a liquid removal capability adjusting step of adjusting a liquid removal capability of the liquid removal device according to determination results in the state determination step.
