Abstract: PURPOSE:To destaticize electrostatically charged charge of a transfer material carrier so that it may become at an optimum level for separating a transfer sheet by setting the output of a separating charger in accordance with the number of transfer times at the time of forming the image. CONSTITUTION:The output of the separating charger 26 is set in accordance with the number of transfer times at the time of forming the image. In the case that the output of a destaticizer 26 is fixed irrespective of increasing the electrostatically charged charge of a dielectric screen at every time of transfer, the excess or the shortage of destaticizing for separation occurs. That means, in the case that the shortage of destaticizing occurs, aerial discharge at the time of separating the transfer sheet and the dielectric screen is increased, so that the toner cannot be prevented from scattering caused on the influence of the discharge, so that the output of the separating charger 26 is made to increase in accordance with the number of transfer times at the time of forming the image. Thus, the electrostatically charged charge of the transfer material carrier which is made different based on the number of transfer times can be destaticized so that it may be set at the optimum level for separating the transfer sheet.

Abstract: PURPOSE:To remarkably enhance the decoloration efficiency of a polymer film to be formed on a resist film and faded by irradiation with light and to improve the form of the resist pattern by incorporating a photochromic compound in the polymer film. CONSTITUTION:The 100pts.wt. of the polymer film contains, preferably, 0.01 - 5.0pts.wt. of the photochromic compound fadable by irradiation with light. Since this photochromic compound is converted into another structure by irradiation with a light specified in wavelength without producing any by product, the absorption of the light in the initial wavelength is greatly reduced, thus permitting the contrast of the light reaching the resist to be greatly elevated and the form of the resist pattern to be enhanced.
