IPC: G03G15/02
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device constituted so that an image is prevented from flowing by suppressing the production of ozon or nitrogen oxide in an electrifying process. SOLUTION: This image forming device is constituted so that a photoreceptor drum(image carrier) is electrified, a latent image is formed on the photoreceptor drum and developed and an AC voltage is impressed on an electrifying roller(electrifying device). Then, an AC current(amplitude and frequency of AC voltage) is lowered than that of a latent image forming time at the electrifying time other than the latent image forming time. Since the AC current is lowered than that of the latent image forming time at the electrifying time other than the latent image forming time, the production of the ozon or the nitrogen oxide is suppressed in the electrifying process. Besides, the image is prevented from flowing caused by conductive substances produced by reaction between filler included in a transfer material and the ozon or the nitrogen oxide.

Abstract: PROBLEM TO BE SOLVED: To improve the life of a metallic dental technic member by introducing a compression stress into the surface layer of the member by mechanical action. SOLUTION: A compression stress is introduced into the surface layer of a member by mechanical action. The compression stress is advantageously introduced into the surface layer by shot peening.
