PURPOSE:To obtain a sharp image in which sensitivity can be improved and fogging is prevented from being generated by forming an electrostatic latent image on the image carrier of an organic photoconductor to be electrified to a positive value by image exposing stage, and applying whole image exposure on a stage between an image exposure stage and a developing stage at the time of developing the electrostatic latent image by the developing stroke. CONSTITUTION:The electrostatic latent image is formed on the photosensitive drum 1 of the organic photoconductor 1a to be electrified to the positive value by the image exposure stroke, and at the time of developing the electrostatic latent image by the developing stage, the whole image exposure is applied on the surface of the organic photoconductor 1a at the stage between the image exposure stroke and the developing stage by an exposure means 3. Thereby, an electric charge remaining in the neighborhood of the boundary of the electric charge generating layer and the electric charge migrating layer of the organic photoconductor 1a is moved to a substrate side, and ground potential is decreased, and the sensitivity of a 1/10 exposure quantity can be increased. In such a way, it is possible to prevent the fogging due to the splash of a developer 5a from being generated, and to form a satisfactory image. |
