PROBLEM TO BE SOLVED: To achieve further improvements in usability. SOLUTION: An image forming apparatus has a latent image forming means for forming a latent image on a photoconductor drum 1, a color development cartridge D for integrally supporting a plurality of color development means Dy, Dc, Dm, Db for visualizing latent image and detachable from a main, a black development cartridge Bk for supporting a monochrome development means which is selectively replaceable with the color development cartridge D, having the same size as the color development cartridge D and visualizing the latent image and a development rotary 11, capable of selectively mounting one of the color development cartridge D and the black development cartridge Bk, sequentially switching a plurality of the color development means Dy, Dc, Dm, Db and placing it facing opposite to the photoconductor drum 1, when the color development cartridge D is mounted. |
