PURPOSE:To obtain the toner which is hardly thermally and plastically deformed and is highly resistant to stresses even with the toner regulated pressure by using a specific polyester resin as an essential component and incorporating at least oxidation type polyolefin therein. CONSTITUTION:The one component developing toner is formed by using the polyester resin (C) obtd. by mixing (A) polyester of a linear low polymer constituted of at least etherified diphenols are arom. dicarboxylic acids and polyester (B) for high polymn. constituted of at least one kind of the compds. selected from the group consisting of at least etherified diphenols, arom. dicarboxylic acids and diols substd. with 3 to 20C aliyl groups, forming urethane bonds by polyisocyanates in the blended state to execute a chain extension reaction as a eccential component, and incorporating at least the oxidation type polyolefin therein. |
