Summary:PURPOSE: To provide the subject elastomer produced by using a specific isocyanurate as a crosslinking agent, having remarkably shortened in-mold crosslinking time without deteriorating the physical properties of the polyurethane elastomer and useful for electrophotographic device, etc. CONSTITUTION: This elastomer is produced by using (A) a polyethylene glycol having a number-average molecular weight of 400-8,000, (B) an isocyanate compound (e.g. tolylene diisocyanate) and (C) tris(2-hydroxyetheyl)isocyanurate of formula as a part or total of the crosslinking agent. The elastomer is preferably produced e.g. by reacting the component A with the component B and reacting the resultant prepolymer with the component C.
