PROBLEM TO BE SOLVED: To obtain a toner for developing an electrostatic latent image excellent in flowability, electrostatic chargeability, developing performance, transferability, fog on a photosensitive material and contamination tendency in a machine. SOLUTION: The toner consists of toner particles having a shape index ML<2> /A of <125 and an external additive. When emission voltage due to carbon originating in the bonding resin of the toner particles is represented by X, emission voltage due to an element originating in the external additive is represented by Y, and X<2/3> and Y are subjected to primary regression to a straight line passing through the origin, the coefft. of correlation of the elements is >0.6. |
