    • A cleaning blade includes an elastic member configured to come into contact with a surface of a member to be cleaned and remove residual matter adhering to the surface of the member to be cleaned. The elastic member satisfies the following requirements a and b: a. The elastic member has a contact portion configured to come into contact with the surface of the member to be cleaned and the contact portion includes a modified layer that contains a cured product of an ultraviolet curable composition containing a (meth)acrylate compound; and b. A value obtained by normalizing a peak area ratio SA/SB of a modified portion with a peak area ratio SA′/SB′ of a portion outside the modified layer is 1.5 or more and 10 or less where SA is a peak area value at 1162 cm−1 and SB is a peak area value at 1533 cm−1 obtained by infrared microspectrometry, and the modified portion is a region that extends 100 μm in a contact portion thickness inward direction from the contact portion on a plane that lies at an equal distance from two surfaces constituting the contact portion.
