The object of this study was to improve electrophotographic photoreceptor using metal free-phthalocyanine dye sensitized system. In here a various types of metal free-phthalocyanine and polymers and hydrazone were used as charge generation material(CGM) and binder, respectively, and also the hydrazone derivative or zinc complex was used as charge transport material(CTM). It was found that $x-H_2Pc$ showed the highest sensitivity among the ${\alpha}-$, ${\beta}-$ and x- metal free-phthalocyanine($x-H_2Pc$) as CGM. The photoreceptor made by $x-H_2Pc$ and hydrazone derivative as CGM and CTM, respectively, showed the highest ratio of dark decay having 73.1% and the good sensitivity of $1.50lux{\cdot}sec$ compared to other photoreceptors.
