摘要： An image forming device is disclosed which comprises an electrophotographic photoreceptor and a flash fixing means. The photoreceptor has a photoconductive layer formed on top of a support substrate, and the photoconductive layer contains a charge generating agent and a charge transport agent therein. The half maximum wavelength region of the charge transport agent's absorption peak is in a visual region that includes the wavelength region of the flash light when its intensity is 50% or greater of its maximum but does not include the wavelength region of the exposure light. This photoreceptor will not produce electrostatic irregularities even if light from the flash fixing means leaks thereon, and its sensitivity and its ability to be electrostatically charged will not decrease even if repeatedly used.
