Cleaning blade, process cartridge, and image forming apparatus

A cleaning blade configured to contact a cleaning target member having a cleaning target surface configured to move, the cleaning blade being configured to clean the cleaning target surface, the cleaning blade comprising:

• a blade body having a distal end surface facing an upstream side in a direction of the movement in a state where the cleaning blade is in contact with the cleaning target member, a lower surface facing a downstream side in the direction of the movement in the state where the cleaning blade is in contact with the cleaning target member, an upper surface sharing a side with the distal end surface and opposed to the lower surface, and a pair of side surfaces each sharing sides respectively with the distal end surface, the lower surface, and the upper surface;
• and
• a blade protrusion that, when a direction in which the pair of side surfaces are opposed is a width direction, a direction in which the lower surface and the upper surface are opposed is a thickness direction, and a direction orthogonal to the width direction and the thickness direction is a height direction, is present at an end portion of the lower surface near the distal end surface, has a shape protruding outward in the thickness direction with respect to the lower surface, and has an inclined surface being a surface continued from the distal end surface and inclined outward in the thickness direction with respect to the lower surface and inward in the height direction with respect to the distal end surface from an end of the distal end surface near the lower surface,
• wherein at least a portion of the inclined surface is a contact surface configured to contact the cleaning target member,
• wherein an end of the inclined surface opposite to the distal end surface is provided a predetermined distance from the lower surface.
