HOUSING ASSEMBLY FOR PHOTORECEPTOR UNIT

摘要

PROBLEM TO BE SOLVED: To provide a housing assembly for a photoreceptor unit which facilitates processing for development, electrification, exposure and transfer and waste toner disposal even when used in a color image forming apparatus, and which increases the reliability of the developing quality of an image because a developing unit can be fixed and undergoes less contamination due to external environment because a photoreceptor drum is exposed little.

SOLUTION: The housing assembly includes: a main housing surrounding at least the half of the large-diameter photoreceptor drum and including a main aperture part on which a plurality of developing units selectively abut and at least one sub aperture part; 1st and 2nd sub housings attached to either side of the main housing; a knob part coupled to the main housing through a hinge; and at least one bracket provided on both side surfaces of the main housing.
