Abstract
The image forming apparatus forms an image on a surface of a recording medium by using ink and treatment liquid. The ink contains coloring material, and the treatment liquid contains at least one of a component which aggregates the coloring material and a component which increases viscosity of the ink. The image forming apparatus includes: a repellent agent deposition device which deposits a repellent agent onto the recording medium to render the surface of the recording medium liquid-repellent; a treatment liquid droplet ejection device which ejects and deposits droplets of the treatment liquid onto the recording medium on which the repellent agent has been deposited; and an ink droplet ejection device which ejects and deposits droplets of the ink onto the recording medium on which the droplets of the treatment liquid have been deposited.
