Abstract
A toner for developing an electrostatic charge image includes an aliphatic polyester resin and a polyester resin having a repeating unit derived from rosin diol.
Claims8
A toner for developing an electrostatic charge image comprising:
- an aliphatic polyester resin;
- and
- a polyester resin including a repeating unit derived from rosin diol, the polyester resin being a polycondensate of rosin diol represented by Formula (II) and dicarboxylic acid:
- wherein in Formula (II),
- R1 represents a stabilized rosin residue or two kinds of groups including a stabilized rosin residue and a monobasic acid group,
- n represents an integer of 1 to 6, where
- when n represents 1, R2 represents a hydrogen atom, and
- when n represents 2 or more, two of the R2s represent a hydrogen atom and the other R2s represent an acetoacetyl group or two or more kinds of groups including an acetoacetyl group and at least one monobasic acid group,
- R3 represents at least one kind selected from a hydrogen atom and a halogen atom, and
- D represents a methylene group or an isopropylene group.
