Abstract
A cartridge for use in an electrophotographic apparatus is loaded with various expendable process units which need periodic replacement such as a charger, developing unit, and cleaning unit.

The cartridge is held in a body of the apparatus in such a manner as to be rotatable between a replaceable position and a set position.
