摘要： PROBLEM TO BE SOLVED: To eliminate the adhesion of foreign matter by peeling static electricity which occurs at the time of peeling a protective film and the unequal adhesion by the static electricity admitted at the time of laminating and using two lens films by including a conductive high polymer having a polythiophene skeleton into a conductive layer disposed on at least one surface of a base material film. SOLUTION: The lens film 10 is formed by laminating the transparent base material film 1, the conductive layer 2 disposed on at least one surface of this base material film 1 and a lens layer 3 consisting of a concave lens or convex lens on the conductive layer 2. The conductive layer 2 contains the conductive high polymer having the polythiophene skeleton. The surface resistance of the conductive layer 2 of the surface light source ms below 10 Ω/square. The lens film 10 prevents the generation of the static electricity up to the surface of the lens layer 3 by the effect of the conductive layer 2 disposed on the base material film 1. Then, an electrostatic charge quantity is less even right after the peeling of the protective film of the lens film 10.

摘要： PROBLEM TO BE SOLVED: To eliminate the peeling of an image and to enhance the weatherability of the image by coating a charged member with a fixer having resin grains dispersed in an insulating dispersion medium. SOLUTION: An electrostatic recording paper 5 is fed onto a drum 1 by a paper feeding roll 6 and an electrostatic latent image is formed by an electrostatic recording head 2. On the electrostatic recording paper 5, the image is formed with a wet developer for the first color by a roller developing machine 3. Then, the electrostatic recording paper is returned to the paper feeding roll 6 and destaticized by a destaticizer 8, at this time. After that, the electrostatic latent image for the second color is formed by the recording head 2 and development for the second color is attained by the developing machine 3. Thus, four color images are formed, uniform electrification by the electrostatic recording head is attained and then, a fixer layer is formed on the electrostatic recording paper by a roller type fixer coating device 4. Then, the fixer has heat processing by a fixing roll 7. Thus, the charged member is coated with the fixer having the resin grains dispersed in the insulating dispersion medium.
