Liquid discharge apparatus and image forming method

A liquid discharge apparatus comprising:

• a discharge portion capable of discharging a liquid;
• a movement portion capable of moving a medium and the discharge portion relatively to each other;
• and
• a control portion capable of executing an image forming operation of forming an image on the medium by a discharge operation of causing the discharge portion to discharge the liquid and a movement operation of causing the movement portion to move the medium and the discharge portion relatively to each other in a movement direction, wherein the image includes a first image formed during a first image forming operation and a second image formed over the first image during a second image forming operation,
• the control portion being capable of changing a first amount of movement that is an amount of movement to be made by the movement operation to form the first image and a second amount of movement that is an amount of movement to be made by the movement operation to form the second image in a case where after the first image is formed, the second image is formed on the first image, and
• the control portion being capable of executing, at least one of decreasing of the first amount of movement and increasing of the second amount of movement so that if the medium is expected to expand due to formation of the first image, the first amount of movement and the second amount of movement are selected in order to restrain over-edge between the first image and the second image.
