Image forming apparatus and method

An image forming apparatus comprising:

• an image forming part that forms an image on a recording material;
• a read part that reads the image formed on the recording material by the image forming part;
• and
• an instruction part that provides instruction for adjustment on a use condition of an image forming member used in the image forming part on the basis of image data read by the read part.

An image forming method comprising:

• forming an image on a recording material;
• reading the image formed on the recording material;
• and
• adjusting a use condition of an image forming member used in the image forming step on the basis of image data read in the reading step.

An image forming apparatus comprising:

• an image forming part that forms an image on a recording material;
• a read part that reads the image formed on the recording material by the image forming part;
• and
• an adjusting part that determines an image misregistration value on the basis of image data obtained by the read part, and, if the obtained misregistration value is larger than a predetermined specification value, adjusts use condition of an image forming member used in the image forming part that exerts an influence on at least one of vertical and horizontal scaling factors of an image, parallelism, squareness, lead registration, side registration, and side skew.
