Abstract
An image forming paper comprises at least pulp, wherein the paper has a spectral reflectance of at least 85% for light diffused-reflected therefrom in a wavelength range of from 440 nm to 640 nm, and a spectral reflectance distribution in which the difference between the maximum and minimum values of the spectral reflectance of the light in the above wavelength range is 5% or less. Therefore, since the amount of light reflected by the paper is large and the reflectance in blue to red regions is constant, color chroma of a color image on the paper is enhanced particularly in green to red regions, and a color reproduction area of the color image is enlarged.
