Abstract:
A cleaning blade includes a polyester urethane rubber. In an IR spectrum measured by μATR on the surface of a contact portion of the polyester urethane rubber at which the cleaning blade comes into contact with a member to be cleaned, a ratio (ISI/ISE) of an intensity (ISI) of a C—N peak due to an isocyanurate group included in the polyester urethane rubber to an intensity (ISE) of a C═O peak due to an ester group included in the polyester urethane rubber is 0.65 or more and 2.50 or less. A siloxane compound is present on the surface of the contact portion of the polyester urethane rubber.
