Electrostatic charge image developing toner, electrostatic charge image developer, and toner container

An electrostatic charge image developing toner comprising:

• an unsaturated polyester resin that contains a structural unit derived from a dicarboxylic acid component having an ethylenically unsaturated bond and a structural unit derived from a dialcohol component represented by the following formula (1):
• where in the formula (1):
• R1 and R2 each independently represent hydrogen or a methyl group, and may be the same as or different from each other,
• L1, L2, and L3 each independently represent a divalent linking group selected from the group consisting of a carbonyl group, an ester group, an ether group, a sulfonyl group, a chain alkylene group which may have a substituent, a cyclic alkylene group which may have a substituent, an arylene group which may have a substituent, and combinations thereof;
• L2 and L3 may be the same as or different from each other;
• and L1 may form a ring with either L2 or L3, and
• A1 and A2 represent a rosin ester group,
• wherein:
• a surface layer portion of the toner contains a crosslinked material of the unsaturated polyester resin;
• and
• a ratio of a resin component which is insoluble in tetrahydrofuran to a total amount of all the resin components is from 0.5% by weight to 5.0% by weight.
