ALUMINUM SUBSTRATE FOR PHOTORECEPTOR AND ITS PRODUCTION

Title:

ALUMINUM SUBSTRATE FOR PHOTORECEPTOR AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP3887030

Kind Code:

B2

Abstract:

PURPOSE: To produce an Al substrate stably having superior surface smoothness.
CONSTITUTION: This Al substrate is a cold-drawn Al substrate having >300μm average length of surface grains in the drawing direction. It is produced by cold-drawing a preform of an Al substrate for a photoreceptor having ≥60μm average length of surface grains in the drawing direction so that the average length of grains in the drawing direction is increased by ≥1.3 times. By the cold drawing, the average length of surface grains in the drawing direction is regulated to >300μm.
