Abstract
An electrostatic charge image developing toner includes: a polyester resin that has a glass transition temperature of about 45° C. or higher and in which a proportion of repeating units derived from fumaric acid in repeating units derived from acid components is 10 mol % or greater and a proportion of repeating units derived from alkenylsuccinic acid in the repeating units derived from acid components is 10 mol % or greater; and a photopolymerization initiator, wherein a content of the photopolymerization initiator is from about 0.5% by weight to about 10% by weight.
