PURPOSE:To provide image forming device capable of reducing the unevenness of image density caused by the dispersion of exposure on the surface of photosensitive paper generated by the roughness/fineness of an exposure pitch. CONSTITUTION:In a wet-type color image forming device, an auxiliary exposure device 1 is arranged in the rear of an exposure device 42 and in front of a prewetting device 43. Therefore, in sheet like photosensitive paper 20 electrostatic charge is imparted by a corona electrifier 41 firstly, electrostatic latent image is formed by an exposure device 42. Surface electrical potential after exposure at this time is higher than prescribed surface electrical potential before development, thereafter, is lowered to the prescribed surface electrical potential by irradiating light outputted from the auxiliary exposure device 1 to the sheet like photosensitive paper 20 and exposing it uniformly. Thus, the dispersion of the surface electrical potential of the photosensitive paper generated by the roughness/fineness of the exposure pitch is reduced. |
