摘要： A discharging device includes first and second electrodes sandwiching therebetween a dielectric member, wherein an alternating voltage is applied between the first electrode and the second electrode to produce electric discharge adjacent to the second electrode. The relation between the alternating voltage and a distance between an end surface of the second electrode to a corresponding end of a region where the electric discharge occurs, is so determined that an intermediate saturation property is exhibited. The level of the alternating voltage is set to provide the intermediate saturation property. With such a discharging device, a member is electrically charged or discharged.

摘要： 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.
