Method for working substrate of photosensitive body

Abstract

Abstract PURPOSE:To prevent attached matter from remaining on the surface of a base body of a photosensitive body by using a specified cutting oil. CONSTITUTION:The cutting oil containing an oiliness improver and/or an extreme-pressure additive in an amount of <=1.0wt.% is used for cutting work for the base body made of an aluminum alloy or the like of the photosensitive body, but both of them may be used in the total amount of <=1.0wt.%. If the content of the one or both is over 1.0wt.%, the tenaciously attached matter hardly removable by rinsing remains on the surface of the base body, and comes to locally change the characteristics of the photosensitive body, and the use of the one or both in an amount of <=1.0wt.% permits the clean surface of the base body and the photosensitive body few in faults to be obtained.
