Abstract: The present disclosure provides a cleaning blade (2) that prevents toner from slipping through the cleaning blade in a long time use. The cleaning blade (2) is used to remove residual toner remaining on a surface of a counterpart member (1) in an electrophotographic image forming device by sliding contact with the counterpart member (1). The cleaning blade (2) includes a support (3) including a plate-shaped portion (31); and a blade part (4) made of polyurethane, and joined to the plate-shaped portion (31) in integral forming. The blade part (4) includes a plate-shaped blade body portion (41) that is joined to a plate surface of the plate-shaped portion (31), and a reinforcing portion (42) that extends from a surface of the blade body portion (41) and is joined to a front end face of the plate-shaped portion (31). The reinforcing portion (42) has a curved surface (421) that curves inward.
