A developing device having a conductive elastomer of a developing agent transferring body which develops an image in a contact or noncontact manner, and an electrophotographic image forming apparatus having the same. The developing device develops a nonmagnetic one component developing agent in a contact development manner on a photosensitive medium on which an electrostatic latent image is formed by an incident scanned beam. The developing device includes a housing in which the developing agent is stored, and a developing agent transferring body which includes a shaft installed to be rotated inside the housing and a conductive elastomer surrounding an outer circumference of the shaft and contacting the photosensitive medium to transfer the developing agent stored in the housing to the photosensitive medium, wherein a thickness of the conductive elastomer is less than 2 mm.
