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.
