摘要： An image forming apparatus of the present invention comprises an image carrying member 2, a photosensitive member 9, a first voltage applying means 13, and an exposure means 5. The image carrying member 2 has an insulating layer 25 formed on a first conductive layer 23. The photosensitive member 9 has a photosensitive layer 93 formed on a second conductive layer 92. The photosensitive member 9 is supported so that the photosensitive layer 93 is opposed to the insulating layer 25 of the image carrying member 2. The first voltage applying means 13 applies a voltage between the first conductive layer 25 and the second conductive layer 92. A pattern-like surface electrode layer 98 is formed on the surface of the photosensitive layer 93 opposed to the image carrying member 2. A second voltage applying means 14 applies a bias voltage to the surface electrode layer 98. The exposure means exposes the photosensitive member 9 to discharge between the pattern-like surface electrode layer 98 and the image carrying member 2, thereby, an electrostatic latent image is formed on the surface of the image carrying member 2.
