| abstract |
The present invention provides a crystalline polyester resin having sharp melt property, satisfying both fixability and blocking characteristics, and having good chargeability, and the crystalline polyester resin for toner satisfies the following relational expression. 25? Tg? 70 and (Tg + 273) / (Mp + 273)? 0.75 In the above formula, Tg (占 폚) represents the glass transition temperature of the crystalline polyester resin for toner, and Mp (占 폚) represents the melting point of the crystalline polyester resin for toner. |
