IMAGE FORMING METHOD

PURPOSE:To obtain a fog-free image which deteriorates less on repetitive use by rubbing the magnetic toner, which is held on a magnetic roll, on the opposite side while exposing the image from a transparent substrate side. CONSTITUTION:A light of a lamp 10 is irradiated from the transparent conductive layer 2 side of a photosensitive body 1 through a slit 8 and an original 9 to the photosensitive body and at the same time the photosensitive body 1 and an original 9 are moved in an arrow direction so that the (semi)conductive toner 6 held on a developing roll 5 having internally a magnet in the state of being impressed with a voltage rubs the surface of the photosensitive body. The toner 6 sticks on the photosensitive body corresponding to the image part (non-exposed part) of the original 9. No exposing is made on the image part of the photosensitive body and therefore the photosensitive body has high surface resistance and the toner 6 having electric charge sticks on the photosensitive body. Since exposure is made on the non-image part, the surface resistance of the photosensitive body decreases and the toner does not stick on the photosensitive body as the quantity of the electric charge decreases.
