Abstract
A supply roller of a developing device for an image forming apparatus and a method of manufacturing the same are provided, which is small and exhibits excellent toner supply properties while preventing occurrence of the ghost phenomenon and toner-filming phenomenon, which cause a deterioration in image quality. The supply roller of the developing device for the image forming apparatus according to the present invention includes a shaft, and a conductive resilient member enclosing an outer circumference of the shaft. The conductive resilient member has a density of about 60 kg/m3 to about 120 kg/m3, and an outer diameter of about 8.0 mm to about 10.0 mm.
