Title: Production of electrophotographic photoconductive member
Inventor: KAWAMURA TAKAHISA
IPC: C22C21/00
Filed: 1995-12-18
Abstract: PURPOSE: To suppress abnormality in the structure such as voids and to suppress decrease in processability or deterioration in characteristics of the processed product by using a base body made of an aluminum alloy consisting of aluminum as the base material and containing a specified amt. of hydrogen. CONSTITUTION: A base body comprising an aluminum alloy in which the amt. of hydrogen is suppressed to <=1.0cc to 100g of aluminum is used, on which a conductive layer is formed. By suppressing the amt. of hydrogen to <=1.0cc to 100g of aluminum, problems caused by abnormality in the structure can be avoided. If the amt. exceeds 1.0cc, defects are produced in the alloy structure, which increases the size and density of voids to produce defects when the alloy is subjected to precision working with a cutting tool. This produces voids of >=5μm size, which is not preferable. It is more preferable that the amt. of hydrogen is <=0.7cc to 100g of aluminum. The member obtd. from this alloy shows uniformity in electric, optical and photoconductive characteristics and realizes an image of high quality with little image defect.
