Abstract
A tandem-type electrophotographic image forming apparatus includes multiple color image forming units using a dry toner, a first black image forming unit using the dry toner, and a second black image forming unit using a wet toner and performs an image formation with the dry toner in a first printing mode and an image formation with the wet toner in a second printing mode. The image formed in the second printing mode with the wet toner is fixed to a recording medium at a temperature lower than the image formed in the first printing mode with the dry toner. Each of the image forming units corresponds to a process cartridge that is removably installable in the tandem-type electrophotographic image forming apparatus and including an image carrier and other image forming components integrally therein.
