Abstract
A cleaning apparatus for an image forming apparatus includes a cleaned member and a cleaning member having a cleaning blade coming into contact with a surface of the cleaned member thereby scraping off a toner, wherein the cleaning blade includes an elastic material having an anisotropy in tensile stress and the cleaning blade shows a deformation, resulting from a tensile stress induced in a direction of load by a friction with the cleaned member, smaller than a breaking elongation of the cleaning blade in the vicinity of a contact portion of the cleaning blade with the cleaned member. In this manner a longer service life of the image forming apparatus can be realized while securing a desired cleaning performance.
