Abstract
An electrostatic image developing toner includes toner base particles including at least a binder resin and a release agent, wherein the binder resin includes a hybrid resin having a polyester resin segment and a styrene-acrylic copolymer segment, and a molecular weight distribution curve of the toner satisfies Formula (1): 1.3≤b/a≤2.5, where, in the molecular weight distribution curve in which a perpendicular line is drawn from a baseline to a peak top having a peak top height to divide the molecular weight distribution curve into a lower-molecular-weight region and a higher-molecular-weight region, a represents a width of the lower-molecular-weight region at a height of 15% of the peak top height, and b represents a width of the higher-molecular-weight region at a height of 15% of the peak top height.
