<p>PURPOSE: A porous polymer membrane, a fluid processing method using the same, and a manufacturing method of an asymmetry porous polymer membrane are provided to properly use in the inkjet application by offering a minimum smearing and gel line. CONSTITUTION: A porous polymer membrane comprises a first microporous skin surface; a second porous surface; a body which is in between the first microporous skin surface and the second porous surface. The first microporous skin surface includes more than about 20 pores/50,000μm^2 of the pore density. The body includes more than about 120 pores/mm^2 of the pore density.
