PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining the output image of high resolution by concentrately performing the developing process in a nip position on a developing sleeve, in which the potential distribution becomes sharpest. SOLUTION: As for this device, the developer carrier 42 in developing means 42, provided with a fixedly arranged insulating cylindrical member 43, and the cylindrical member 43 is, provided with the developing area image forming member 45 composed of a conducting material, extend/located in a straight line state in the lengthwise direction of the cylindrical member 43 in parallel with the photoreceptor drum 1 on the closest position to the photoreceptor drum 1. The conducting film 44 is arranged on the periphery of the cylindrical member 43 and the developing area image forming member 45. |
