摘要:
An electrostatic latent image developing dry toner and the like are provided, in which toner remaining after transfer can be recovered during developing with or without having a blade cleaning stage for promoting friction of an electrostatic latent image holding member. The electrostatic latent image developing toner contains toner particles containing a binder resin and a colorant and monodisperse resin particles having a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less. A method of producing the above toner first mixes monodisperse resin particles, which have a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less, with toner particles containing a binder resin and a colorant, and adds an inorganic compound having a diameter smaller than that of the resin particles with a shear lower than the first mixing.
