Claims4
A cleaning member adapted to abut a member having oil adhered thereon, comprising:
- a surface layer in contact with the member having oil adhered thereon, said surface layer adsorbing the oil adhered on the member;
- and
- an inner layer disposed at a side away from the member relative to said surface layer for adsorbing the oil adhered on the member,
- wherein an oil adsorbing ability of said inner layer is larger than that of said surface layer;
- and
- wherein said surface layer is a non-woven cloth, wherein said non-woven cloth is made of fibers an average thickness of which is smaller than 10 .mu.m, and 70% or more of said fibers each has a thickness smaller than 10 .mu.m and a density of said fibers being in a range of 0.05-0.80 g/cm.sup.3.
