In a cleaning blade and an image-forming apparatus using a cleaning means having the cleaning blade, the cleaning blade is composed of an edge portion which is brought into contact with the image-bearing member and a support portion which brings the edge portion into contact with the image-bearing member, where the value at a peak temperature (t1) of a loss tangent of the edge portion, tan &dgr;1, is smaller than the value at a peak temperature (t2) of a loss tangent of the support portion, tan &dgr;2, and a curve which represents the temperature dependence of the loss tangent of the edge portion and a curve which represents the temperature dependence of the loss tangent of the support portion intersect at t1° C. or above to t1+40° C. or below. These can maintain the surface state of a photosensitive member that does not cause any smeared images or melt adhesion of toner even when non-magnetic toners are used, promising a great improvement in reliability, and also can deal with any situations even when the productivity has dramatically been advanced.
