Abstract
An oil coating roller comprising a porous round-rod-like molded product, a heat-resistant fiber felt layer provided on an outer circumference of the porous round-rod-like molded product, and a porous film applied onto an outer circumference of the felt layer. The porous round-rod-like molded product contains heat-resistant fibers bound to each other by a binder, and has fine communicating voids free from the binder among the fibers and evenly distributed pores having a pore size in a range of from 0.05 to 2 mm and a total void percentage in a range of from 30 to 90%. The porous round-rod-like molded product is impregnated with silicone oil. The heat-resistant fiber felt layer has a thickness in a range of from 0.5 to 5 mm. The porous film has a thickness in a range of from 15 to 130 &mgr;m, a mean pore size in a range of from 0.1 to 3.0 &mgr;m, a porosity in a range of from 60 to 90% and an air permeability in a range of from 3 to 1500 sec per 100 cc.
