Embodiment 1

[0042] First, referring to Figs. 1 and 2, an example of an electrophotographic image forming apparatus in which a process cartridge unit constructed according to the present invention is mountable will be described. The image forming apparatus in this embodiment is one that outputs an image by receiving image information from a host computer, and one of the process cartridge parts is detachably mounted so that the photoconductor in the form of a drum whose service life has expired is replaced with a brand new one , that is, photoconductive drums, or laser beam printers that fill imaging devices with consumables such as developer. First, the image forming apparatus and process cartridge components in this embodiment will be described with reference to FIGS. 1 and 2. FIG.

[0043] The process cartridge unit C in this embodiment includes a plurality of elements as elements for performing the image forming process for the image forming apparatus in this embodiment. More specifica...
