发明名称 Developer, image forming unit and image forming apparatus
摘要 A developer has a molecular weight distribution of its tetrahydrofuran soluble portion measured by a gel permeation chromatography. In the molecular weight distribution, the main peak is in a range from 2×103 to 3×104 weight-average molecular weight (Mw), the shoulder peak is in a range from 200 to 500 Mw, and a half-value width of the main peak is equal to or less than 50000. A glass-transition temperature Tg of the developer is a range from 55° C. to 80° C.
