An image is formed with an electrostatic latent image-developing toner that includes toner base particles and titanium oxide serving as an external additive. The toner base particles containing a binder resin, a colorant, and a charge control agent. The titanium oxide is attached to surfaces of the toner base particles and containing titanium oxide A and titanium oxide B. Each of the titanium oxide A and the titanium oxide B has a predetermined particle diameter and a predetermined volume resistivity. The liberation rate of each of the titanium oxide A and the titanium oxide B in the toner is within a predetermined range.
