  • Patent number: 7813690
    Abstract: A cleaning device removes a toner attached to an image carrier of an electrophotographic-type image forming apparatus. The cleaning device includes a cleaning blade, a housing and a block member. The cleaning blade is in contact with a surface of the image carrier to removes the toner. The housing stores the toner removed by the cleaning blade. The block member causes the toner to temporarily remain the toner in a vicinity of a distal end of the cleaning blade. The block member is formed of a sheet-shaped elastic member. One side of the block member is fixed to the housing. A repulsive force against bending in an end portion of the block member in a longitudinal direction is substantially smaller than a repulsive force against bending in a center portion of the block member.
