Abstract

PURPOSE: To obviate the degradation in optical performance even in high-humidity environment and make charging phenomena difficult to occur by providing specific lamination layers on the light input and output end faces of graded index type optical transmission bodies in the image forming element used for the optical system of copying machines, etc.
CONSTITUTION: Plural graded index type optical transmission bodies 2 are arrayed and fixed by way of fillers in a holding member 3 composed of a metal plate or the like having been colored black. Such element 1 is held for a required time under heating up to temperatures of 50 to 55°C, whereby it is released of its internal stresses. Next, the input and output end faces 4 of the element 1 are cleaned with methyl alcohol or the like. On the other hand, tetrafunctional SiCl4 is acted in univalent alcohol or esters while being added with specified water content, whereby the vitrified colloidal dispersion system material of partially hydrolyzed product is formed, which is then evenly coated on the end faces 4. Next, the solvent is allowed to evaporate in an atmosphere of about 50°C, whereby the lamination layers 5 are formed
