1. A toner comprising a toner particle containing a binder resin, wherein
the binder resin contains a block polymer and a styrene-acrylic resin; the block polymer has a vinyl polymer segment and a crystalline polyester segment; the polyester segment is a segment produced by condensation polymerization of the following (I), (II) and (III): (I) a dicarboxylic acid having carboxyl groups at both terminals of a linear alkane having 2 to 16 carbon atoms; (II) a diol having hydroxy groups at both terminals of a linear alkane having 2 to 16 carbon atoms; and (III) an alkane compound having 3 to 24 carbon atoms, or an alkyl ester, lactone or acid anhydride compound derived from the alkane compound; the alkane compound is at least one compound selected from the group consisting of the following (a) to (f): (a) a branch alkanedicarboxylic acid; (b) a branch alkanediol; (c) a branch alkane monohydroxy monocarboxylic acid; (d) a linear alkanedicarboxylic acid at least one of carboxyl groups of which is linked to a moiety other than a terminal; (e) a linear alkanediol at least one of hydroxy groups of which is linked to a moiety other than a terminal; and (f) a linear alkane monohydroxy monocarboxylic acid at least one of carboxyl group and hydroxy group of which is linked to a moiety other than a terminal; the block polymer has a melting point (Tm) of 50° C. to 95° C.; and the binder resin contains the block polymer at 2.0% by mass to 50.0% by mass. |
