摘要： 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.

摘要： A fixed roller is laterally axially supported by a movable body so as to ow an axial center line of the fixed roller to extend in parallel to a lateral direction, and driven to rotate an upper peripheral surface of the fixed roller backward, and a plurality of split press rollers respectively having the axes inclined by a predetermined angle with respect to an axial center line of the fixed roller as viewed in plan are arranged in a row in a lateral direction above the fixed roller in the manner of supporting the split press rollers by press roller frames. The split press rollers are energized to the descending side by oil-hydraulic cylinders respectively provided between a frame of the body and the press roller frames so as to bring the lower peripheral surface side of each split press roller into contact with the upper peripheral surface of the fixed roller under the action of pressure.
