The present disclosure provides a cleaning blade capable of improving chipping resistance. A cleaning blade includes a blade part made of polyurethane and having an edge that comes in slidable contact with a mating part. The edge includes: a base material containing polyurethane; an impregnated layer containing polyurethane in the base material and a cured acrylic product and present from the surface through to the inside of the base material; and a particle layer containing particles supported by the surface of the base material. The average particle diameter of the particles is between 3 nm and 100 nm, inclusive. The thickness of the impregnated layer is 30 nm or greater and less than 1000 nm. The edge has an area ratio of the particle layer to the impregnated layer that is between 5% and 30%, inclusive in a cross section perpendicular to the surface of the base material.
