A resin roller ( 10 ) is produced by disposing a core body ( 21 ) in a forming metal mold ( 1 ) having a cylindrical metal mold ( 13 ) and core supporting members ( 14 ) furnished at both edge parts of the cylindrical metal mold ( 13 ) as well as causing the core supporting members ( 14 ) to hold said both edge parts, and pouring a forming resin into the metal mold and solidifying it. The resin roller ( 10 ) has the core body ( 21 ) of the same outer diameter over a full length and a cylindrical resin-formed body ( 12 ), sealing members ( 24, 26 ) are furnished around the core body ( 21 ) in the vicinity of both edge parts of the resin-formed body ( 12 ), and the core body ( 21 ) is disposed such that the sealing members ( 24, 26 ) contact edge faces ( 14 a) at sides of a roller forming space of the core supporting members ( 14 ).
