Abstract
A cleaning blade includes a blade substrate, a blade support, and a coating layer. The blade substrate includes an elastic body having a tip portion to be in contact with a surface of an object to clean the surface of the object. The blade support supports the blade substrate. The coating layer coats at least the tip portion of the elastic body to form a tip ridge in contact with the surface of the object. The coating layer has a developed interfacial area ratio (Sdr) of 1.2% or more and 1.8% or less in a 100 μm square region inward from the tip ridge of the coating layer on the blade substrate.
