摘要： An application device includes a conveyer to convey a recording medium, an application roller to apply a treatment liquid to the recording medium, a pressure roller to sandwich the recording medium with the application roller to press the recording medium against the application roller, and a winding member to form a curved conveying path to have the recording medium curved along a conveying direction to wind the recording medium around the pressure roller. The pressure roller comes in contact with the application roller when applying the treatment liquid and separates from the application roller when not applying the treatment liquid. A predetermined positional relationship is maintained between the pressure roller and the winding member while the pressure roller moves close to the application roller to be in contact with the application roller, or the pressure roller moves away from the application roller to be separated from the application roller.
