PURPOSE:To stably charge an image holder and to stably carry out good image formation by using an image formation device in which a charging brush is connected to the surface of the image holder so as to make the image holder charged, without making the toner remained in the image holder adhered to the charging brush and accumulated thereby. CONSTITUTION:A photosensitive material 1 is charged to a predetermined polarily by connecting a charging brush 2 of the brush density of 5-200,000/inch<2> to the surface of the photosensitive material 1, and the electrostatic potential image correspondent to image information is formed by an optical system 3, on the surface of thus charged photosensitive material 1, while a toner 5 to which a fluidization agent of granular dimetrical ratio of 1/20-1/1000 to toner grain, is supplied to the surface of the toner grain, from a developing device 4 to the surface of the photosensitive material 1 on which the electrostatic potential image is formed, and the electrostatic potential image formed on the surface of the photosensitive material 1 is thus made visible. |
