Image formation apparatus that forms first toner image by using bright toner containing bright pigment and second toner image by using non-bright toner

An image formation apparatus comprising:

• a first image formation unit that includes a first image carrier and is configured to form a first toner image on the first image carrier by using a bright toner containing a bright pigment;
• a second image formation unit that includes a second image carrier and is configured to form a second toner image on the second image carrier by using a non-bright toner not containing the bright pigment;
• a transfer unit configured to transfer the first toner image and the second toner image to a transfer body;
• a first waste toner storage portion that is configured to store the bright toner not transferred from the first image carrier and collected from the first image carrier as a waste toner;
• a second waste toner storage portion that is configured to store the non-bright toner not transferred from the second image carrier and collected from the second image carrier and the bright toner collected from the transfer body as waste toners;
• and
• a controller that controls the transfer unit, wherein
• the controller is configured to control a proportion of the bright toner of the first toner image to be collected as the waste toner from the first image carrier into the first waste toner storage portion such that the proportion in a case where the second toner image is superimposed to the first toner image formed on the transfer body is higher than the proportion in a case where the second toner image is not superimposed to the first toner image formed on the transfer body.
