Abstract
The invention disclosed relates to an image forming method using long wavelength light source. The method comprises a first step of charging and irradiating a photosensitive member to thereby form a negative electrostatic latent image; a second step of developing said negative electrostatic latent image by a reversal development; a third step of irradiating said photosensitive member with long wavelength light; a fourth step of transferring the developed electrostatic latent image to a paper; and a fifth step of irradiating said photosensitive member with long wavelength light. Said irradiating light used at the third step has the same or close wavelength region as the one used at the first step, and further, said irradiating light used at the fifth step has the same or close wavelength region as the one used at the first and third steps.
