What is claimed is: 1 . A resin composition comprising: an aromatic polyether ketone resin (I); and a fluorine-containing copolymer (II), the resin composition satisfying an r2/r1 ratio of 1.60 or lower, wherein r1 is an average dispersed particle size of the fluorine-containing copolymer (II) and r2 is an average dispersed particle size of the fluorine-containing copolymer (II) after melt flow rate measurement at 380° C. and a load of 5000 g and with a preheating time of five minutes in conformity with ASTM D1238. 2 . The resin composition according to claim 1 , wherein the aromatic polyether ketone resin (I) has a melting point of 300° C. to 380° C. 3 . The resin composition according to claim 1 , wherein the aromatic polyether ketone resin (I) has a glass transition temperature of 130° C. to 220° C. 4 . The resin composition according to claim 1 , wherein the fluorine-containing copolymer (II) has a melting point of 200° C. to 323° C. 5 . The resin composition according to claim 1 , wherein the fluorine-containing copolymer (II) is a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1): CF 2 ═CF—Rf 1 (1) wherein Rf 1 is —CF 3 or —ORf 2 , where Rf 2 is a C1-C5 perfluoroalkyl group. 6 . The resin composition according to claim 1 , wherein the aromatic polyether ketone resin (I) and the fluorine-containing copolymer (II) are present in a mass ratio (I):(II) of 99:1 to 30:70. 7 . The resin composition according to claim 1 , further comprising a fibrous filler (III). 8 . A pellet obtained by molding the resin composition according to claim 1 . 9 . A molded article formed from the resin composition according to claim 1 . 10 . A molded article formed from the pellet according to claim 8 .
