| 摘要 |
The present invention provides a toner for developing an electrostatic latent image which is capable of obtaining sufficient image density and preventing transfer failure even in a state that a toner is likely to be deficient in charge amount or charge distribution such as when the consumption rate of toner is high or in the early stage of printing. A toner for developing an electrostatic latent image is a toner comprising a colored particle containing a colorant and a binder resin, wherein a work function X (eV) of the toner obtained in measuring work function and a gradient A (1/eV) of a normalized photoelectron yield with respect to an excitation energy calculated from a formula "normalized photoelectron yield/excitation energy" are in the ranges of 5.35<X<5.60 and A-55X+290>0, is disclosed.
