A pair of elastic seals disposed at both ends of a cleaning blade of a cleaning apparatus include a back surface contact portion that is in contact with a back surface of the cleaning blade, a drum contact portion that is in contact with a photosensitive drum, and a side end surface facing portion connecting the back surface contact portion to the drum contact portion. Where the distance between one side end surface and another side end surface of the cleaning blade is L0, the distance on a side adjacent to the back surface contact portion, between the side end surface facing portion of one elastic seal and the side end surface facing portion of another elastic seal is L1, and the distance on a side adjacent to the drum contact portion is L2, L1<L0<L2. |
