METHOD FOR PRODUCING METAL CYLINDER, METHOD FOR PRODUCING SUBSTRATE FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND METAL SLUG FOR IMPACT PRESSING

A method for producing a metal cylinder includes preparing a metal slug having a surface adjusted so that the crystal grain diameter at a depth of 10 μm from the surface is smaller than that at a depth of 100 μm from the surface, and the crystal grain diameter at a depth of 10 μm from the surface is...

Zusammenfassung:	A method for producing a metal cylinder includes preparing a metal slug having a surface adjusted so that the crystal grain diameter at a depth of 10 μm from the surface is smaller than that at a depth of 100 μm from the surface, and the crystal grain diameter at a depth of 10 μm from the surface is 30 μm or more and 120 μm or less; and forming a cylinder by impact pressing of the metal slug having the surface as a bottom.
