Abstract
An image forming process module is provided having an integrated photoreceptor unit and development unit, and an image forming apparatus having the same. The image forming process module includes a photoreceptor unit having at least one photoreceptor on which an electrostatic latent image is formed. A development unit is installed around the outer surface of the photoreceptor and having a plurality of development assemblies for developing the latent image, thereby forming a visual image. A fixing frame is detachably installed to a main body of an image forming apparatus for fixing the photoreceptor unit and the development unit to be integrated into a single module. The image forming process module has the enhanced assembly and replacement efficiencies because the photoreceptor unit and the development unit are simultaneously installed to and uninstalled from a main body of an image forming apparatus as a single module.
