Liquid application device, image forming system, and method of controlling liquid application device

An image forming system, comprising:

• an image forming apparatus to eject a color material to a target to form an image on the target;
• and
• a liquid application device to apply a liquid to the target before the image forming apparatus forms the image on the target,
• the liquid application device including
• an application roller to apply the liquid to the target,
• a container to store the liquid;
• a supply roller to rotate with the application roller, the supply roller being immersed in the liquid in the container and supply the liquid to the application roller,
• a transfer unit to contact the target with the application roller and cause the application roller to apply the liquid to the target, and
• a controller to control an operation of the liquid application device,
• wherein, in a state in which the transfer unit does not contact the target with the application roller, the controller controls the supply roller to rotate and stop at a position different from a pre-rotation position of the supply roller.
