Image formation system, method for determining image formation condition and storage medium storing program therefor

An image formation system comprising:

• an image forming part including a primary transfer mechanism and a secondary transfer mechanism, the image forming part forms images on recording materials;
• and
• a control parameter modification part that modifies a control parameter used in an image forming process of the image forming part, wherein
• each time the control parameter modification part modifies the control parameter, the image forming part sequentially forms test images on the recording materials on the basis of the modified control parameter.

An image formation system comprising:

• an image forming part that forms images on recording materials;
• and
• a control parameter modification part that modifies a control parameter used in an image forming process of the image forming part,
• wherein each time the control parameter modification part modifies the control parameter, the image forming part sequentially forms test images on the recording materials on the basis of the modified control parameter, and
• wherein the image forming part includes a fixing member that heats and presses the image formed on the recording material to fix them, and passes a dummy recording material through the fixing member before forming the test images on the recording materials.
