Abstract
A method applicable to an image forming apparatus with a lubricant to be applied to a surface of a photoreceptor for measuring surface roughness of the surface of the photoreceptor after lubricant application, the method including: a first step of measuring a surface profile of the photoreceptor and obtaining first data indicating the surface profile; a second step of generating second data on the basis of the first data, the second data indicating arithmetic mean roughness Ra within a predetermined range; and a third step of calculating a difference value ΔRa between second data before lubricant application and second data after lubricant application obtained by performing the first and second steps both before and after the lubricant is applied to the photoreceptor.
