A method for producing an electrophotographic photoreceptor drum is provided to impart excellent environmental stability, stability over time and surface durability to an OPC(organic photoconductor) drum, thereby realizing high-quality printing images even under high or low temperature or humidity after a long time, and increasing the number of printable pages. A method for producing an electrophotographic photoreceptor drum comprises the steps of: forming a charge generating layer by coating a charge generating composition containing an indium-based titanium phthalocyanine compound comprising indium mixed with phthalocyanine onto an aluminum pipe having an allumite plating layer; and forming a charge transport layer by coating a charge transport composition containing a stilbene backbone-containing compound and triphenyldiamine(TPD) compound. In the method, the charge generating composition is obtained by 0.5-5 wt% of the indium-based titanium phthalocyanine compound and 0.5-5 wt% of a binder resin into 90-99 wt% of a solvent, wherein the indium-based phthalocyanine compound comprises 70-99 w% of a titanium phthalocyanine compound and 30-1 wt% of indium. The charge transport composition is obtained by dissolving 5-12 wt% of a charge transport material comprising a stilbene backbone-containing compound and triphenyldiamine(TPD) compound, 5-15 wt% of a binder resin, and 0.001-2 wt% of a silane coupling agent into 71-89.999 wt% of a solvent, wherein the stilbene backbone-containing compound is present in an amount of 2-5 wt% of the total charge transport composition, and the TPD compound is present in an amount of 3-7 wt% of the total charge transport composition.
