Zusammenfassung:	To provide a polyester for toner and a resin particle having excellent hot offset resistance, granulatability, and chargeability.SOLUTION: A method for producing a resin particle includes a step in which a chemical structure represented by a general formula (1) and/or (2) of a polyester resin with a number average molecular weight of 1000-10000 is combined with a metal compound in an aqueous medium. [In the general formulae (1) and (2), R1 is a hydrogen atom or an alkyl group, and R2 independently represent an alkylene group or oxyalkylene group].SELECTED DRAWING: None 【課題】耐ホットオフセット性、造粒性、及び帯電性に優れるトナー用ポリエステル及び樹脂粒子を提供することを目的とする。【解決手段】数平均分子量が１０００～１００００であり、一般式（１）及び／又は（２）によって表される化学構造部分を有するポリエステル樹脂の一般式（１）又は（２）の化学構造部分と金属化合物が水性媒体中で結合する工程を含む樹脂粒子の製造方法である。［一般式（１）及び（２）中、Ｒ１は、水素原子又はアルキル基を表し、Ｒ２はそれぞれ独立にアルキレン基又はオキシアルキレン基を表す。］【選択図】なし
