Image forming method

Abstract

Abstract PURPOSE:To always record by a well-balanced color, by developing a latent image by a first toner for allowing a light beam of a wavelength component outside of a visible light area, and subsequently, forming a latent image by executing an image exposure by the light beam having said wavelength component, and developing it by a second toner. CONSTITUTION:A first latent image is formed by executing an image exposure to an image forming body having a photoconductive layer, developed by the first toner having a spectral transmittivity characteristic for allowing a light beam of a waveform component outside of a visible light area to transmit through substantially, and subsequently, a second latent image is formed by executing an image exposure to the image forming body by a light beam having said wavelength component, and developed by the second toner. For instance, when the spectral transmittivity characteristic of each toner is shown in the figure, when a light beam whose wavelength is >=750nm is used for an image exposure, even if any toner is developed first, a latent image of a large contrast can be formed by the subsequent image exposure. Accordingly, a toner whose surface reflection is comparatively small on a transfer material can be placed on other color, and a satisfactory color can be expressed.
