Cleaning apparatus and process cartridge

A cleaning apparatus that is detachable from an apparatus main body of an image forming apparatus, comprising:

• an image bearing member;
• a blade member which includes an elastic member constituted of an elastic body contacting the surface of the image bearing member, and a support member supporting the elastic member;
• and
• a frame which rotatably supports the image bearing member and to which the support member is fixed, wherein
• the support member has a first surface that extends in a rotation axis direction of the image bearing member, and a second surface that includes a normal vector which intersects with a normal vector of the first surface and extends in the rotation axis direction, and
• in the rotation axis direction, the first surface is fixed by two fixing members so as to contact two fixed portions of the frame, and a vibration absorbing member, of which length in the rotation axis direction is not more than ¼ the length of the second surface in the rotation axis direction, and of which loss factor tan δ, measured when vibration at a 100 Hz frequency is applied at a measurement temperature 23° C.±2° C. is at least 0.6 and not more than 2.0, is disposed between the frame and the second surface, so that the vibration absorbing member is located in a middle point between the two fixed members in the rotation axis direction.
