PURPOSE:To allow the development of a digital latent image and an analog latent image to be executed by the same image forming device by using nonmagnetic toner particles which are specified in grain size, content and volume average grain size. CONSTITUTION:The nonmagnetic toner which contains 12 to 60number % nonmagnetic toner particles having <=5mum grain size, contains 1 to 33 number % nonmagnetic toner particle having 8 to 12.7mum grain size, contains <=2.0vol.% nonmagnetic toner particles having >=16mum grain size and has the grain size distribution of 4 to 10mum volume average grain size of the nonmagnetic toner is used in the image forming method for transporting the nonmagnetic toner to a developing section to develop the images while regulating the toner to a thin thickness on a toner carrier. The digital latent image and the analog latent image are simultaneously developed to the sensible images in this way. |
