A toner containing toner particles has a particular weight-average particle diameter, containing therein toner particles with another particle diameter in a predetermined number percentage of the number of the toner particles. A releasing agent contained in the toner particles has a particular endotherm ratio (Q/q), that is measured, using a differential scanning calorimeter (DSC), wherein q is the endotherm (muV.min/mg) of the releasing agent contained in predetermined classified and sampled toner particles, assessed per unit amount of the sampled toner particles, and Q is the endotherm (muV.min/mg) of the releasing agent contained in the toner particles of the toner in its entirety, assessed per unit amount of the toner particles. A method of producing the toner, and a method of forming images, using the toner, and a toner container or cartridge containing therein the toner are disclosed. |
