摘要

An image forming apparatus (1), includes: a mainframe (2); a developing unit (18) including a developing agent container (32) that contains a developing agent and a developing agent carrier (34) that carries the developing agent; and an image carrying unit (19) including an image carrier (44) that carries a developing agent image formed by an electrostatic latent image being developed by the developing agent carried on the developing agent carrier (34). The developing unit (18) is attachable to and detachable from the image carrying unit (19). The developing unit (18) is loadable in and unloadable from the mainframe (2) in a state where the developing unit (18) is integrally attached to the image carrying unit (19). <IMAGE>
