Abstract
An electrostatic latent image developing toner includes toner particles each including a toner core () and a shell layer () disposed over a surface of the toner core (). The toner core () contains a polyester resin. The shell layer () includes: first resin particles () having a number average primary particle diameter of at least 30 nm and less than 70 nm and a glass transition point of less than 80° C.; and second resin particles () having a number average primary particle diameter of 70-200 nm and a glass transition point of at least 80° C. A percentage of an area of the toner core () covered with the first resin particles () relative to a surface area of the toner core () is 40-80%. A ratio of total mass of the second resin particles () to total mass of the first resin particles () is 0.5-2.0.
