A color image forming apparatus capable of preventing an image skew by maintaining parallelism of scanning directions between respective photosensitive mediums and between the photosensitive medium and a transfer belt within a certain range. The color image forming apparatus includes an ITU/OPC cartridge, as a single unit, wherein a plurality of photosensitive mediums (OPC) and an intermediate transfer unit (ITU) are integrally mounted. In the ITU/OPC cartridge, an OPC frame and the ITU frame respectively supporting the OPC and the ITU are separably connected, so that the OPC and the ITU having different lifespan can be independently replaced.
