Abstract
A binder resin for toner includes a carboxy group-containing vinyl resin (C), a glycidyl group-containing vinyl resin (E), a reactant thereof, and a fatty acid metal salt (M), in which the carboxy group-containing vinyl resin (C) includes a high molecular weight vinyl resin (H) having a peak in a region in which the molecular weight is equal to or more than 2.5×10and equal to or less than 1.2×10in the molecular weight distribution of a THF soluble content and a low molecular weight vinyl resin (L) having a peak in a region in which the molecular weight is equal to or more than 2×10and equal to or less than 2×10in the molecular weight distribution of a THF soluble content. The reactant of the carboxy group-containing vinyl resin (C) and the glycidyl group-containing vinyl resin (E) is formed in the presence of the fatty acid metal salt (M).
