Abstract
A cleaning blade includes an image region and a non-image region in which Young's moduli at positions separated by a distance of L μm from an edge portion in contact with an photosensitive drum are respectively defined as Yand Y', Yand Y′are 10 mgf/μmor more and 400 mgf/μmor less, Y/Yis 0.5 or less, [{(Y−Y)/Y}/(20−0)] is equal to or more than [{(Y−Y)/Y}/(50−20)] and, the Young's modulus Y≦the Young's modulus Y′where L satisfies 0≦L ≦100 μm.
