Abstract
By utilizing an electrophotographic image forming process, a reversal image can be obtained in the following manner: PA0 charging a photosensitive member; PA0 forming an electrostatic latent image in a charged surface of the photosensitive member; PA0 developing the electrostatic latent image formed on the photosensitive member by using white toner; PA0 charging the photosensitive member again; PA0 developing the surface of the photosensitive member by using other toner different in color from the white toner; and PA0 transferring the toner image formed on the photosensitive member onto a paper sheet.
