In a cleaning device having a cleaning blade which is abutted against an image bearing member that bears an image and cleans the surface of the image bearing member, the cleaning blade includes at least a first rubber layer which is abutted against the image bearing member; and a second rubber layer that supports the first rubber layer; wherein the tandelta peak temperature obtained by a dynamic viscoelasticity test of the first rubber layer is a value close to the surface temperature of the image bearing member; and wherein the tan delta peak temperature obtained by a dynamic viscoelasticity test of the second rubber layer is lower than the tandelta peak temperature of the first rubber layer.
