Image forming apparatus, image forming method, and storage medium

An image forming method comprising:

• discharging a liquid onto a recording medium, the liquid including a metallic ink and a color ink;
• irradiating the liquid on the recording medium with light;
• alternately performing a main scanning movement and a sub-scanning movement, the main scanning movement in which positions where the liquid is discharged and the light is emitted is moved relative to the recording medium in a main scanning direction, the sub-scanning movement in which the positions where the liquid is discharged and the light is emitted is moved relative to the recording medium in a sub-scanning direction perpendicular to the main scanning direction;
• discharging the metallic ink in a region of the recording medium in a former main scanning movement;
• discharging the color ink in the region in which the metallic ink has been discharged, in a latter main scanning movement after the former main scanning movement;
• irradiating the region in which the color ink has been discharged with the light;
• and
• irradiating the region in which the metallic ink has been discharged with the light, in an intermediate main scanning movement after the former main scanning movement and before the latter main scanning movement.

A non-transitory storage medium storing program codes which, when executed by one or more processors, cause the one or more processors to perform an image forming method, the method comprising:

• discharging a liquid onto a recording medium, the liquid including a metallic ink and a color ink;
• irradiating the liquid on the recording medium with light;
• alternately performing a main scanning movement and a sub-scanning movement, the main scanning movement in which positions where the liquid is discharged and the light is emitted is moved relative to the recording medium in a main scanning direction, the sub-scanning movement in which the positions where the liquid is discharged and the light is emitted is moved relative to the recording medium in a sub-scanning direction perpendicular to the main scanning direction;
• discharging the metallic ink in a region of the recording medium in a former main scanning movement;
• discharging the color ink in the region in which the metallic ink has been discharged, in a latter main scanning movement after the former main scanning movement;
• irradiating the region in which the color ink has been discharged with the light;
• and
• irradiating the region in which the metallic ink has been discharged with the light, in an intermediate main scanning movement after the former main scanning movement and before the latter main scanning movement.
