PURPOSE:To enable prevention of the crystallization of a selenium photosensitive body which is relatively easily crystallizable even if such photosensitive body is used by incorporating a filler consisting essentially of titanium oxide into a copying material. CONSTITUTION:Wood chips are digested, bleached and fine selected in a process for production of the copying paper and the filler, sizing and fixing are added thereto in a beating stage. The filler improves stiffness, opacity and whiteness of the paper and smooth the paper. The titanium oxide having 0.3mum grain size is compounded at 6pts.wt. with the filler. Copying is executed by using the copying paper which is the neutralized paper produced by using 5-15pts.wt. such filler by 100pts.wt. base. The crystallization of the selenium photosensitive body which is relatively easily crystallizable is prevented or is made hard to crystallize even if such body is used. The life of the copying machine is thus extended. |
