Disclosed is an electrostatic charge image developing toner excellent in charging characteristics such as charge rise characteristics and charging stability, particularly in a low temperature and low humidity environment and a high temperature and high humidity environment. An electrostatic charge image developing toner is an electrostatic charge image developing toner containing an external additive, and the external additive is made of a silica material obtained by a sol-gel method using a hydrophobic treatment agent. Hydrophobized, large-diameter silica fine particles having a volume average primary particle size of 60 to 150 nm are included, and the large-diameter silica fine particles have an average carbon content of more than 3.0% by mass and 5.0% by mass or less. It is characterized by being. [Selection figure] None |
