Abstract:
There is provided a toner set including a yellow toner, a cyan toner and a magenta toner, the toners each comprising an external additive and colored resin particles comprising a binder resin, a colorant and a charge control agent. An absolute value of an average of q/d for any of the yellow, cyan and magenta toners is expressed by charge amount q (fC) and particle diameter d (μm). It is obtained by measurement using an electric field detachment-type charge amount distribution measurement device. It is in a range of 2.0 to 6.5 fC/10 μm, and a standard deviation (SD) of q/d is 13 fC/10 μm or less. A difference between average values of q/d for any two of the yellow, cyan and magenta toners is 2.0 fC/10 μm or less. A difference (ΔSD) between standard deviations of q/d for the two toners is 5.0 fC/10 μm or less.

Claim (Index 1):
A toner set comprising a yellow toner, a cyan toner and a magenta toner, the toners each comprising an external additive and colored resin particles comprising a binder resin, a colorant and a charge control agent,\n wherein an absolute value of an average of q/d for any of the yellow, cyan and magenta toners which is expressed by charge amount q (fC) and particle diameter d (\u03bcm) and which is obtained by measurement using an electric field detachment-type charge amount distribution measurement device after the following frictional charge treatment, is in a range of 2.0 to 6.5 fC/10 \u03bcm, and a standard deviation (SD) of q/d for any of the yellow, cyan and magenta toners is 13 fC/10 \u03bcm or less; wherein a difference (\u0394q/d) between average values of q/d for any two of the yellow, cyan and magenta toners is 2.0 fC/10 \u03bcm or less, and a difference (\u0394SD) between standard deviations of q/d for the two toners is 5.0 fC/10 \u03bcm or less: [Frictional Charge Treatment]\n first, 9.5 g of a non-coated Mn\u2014Mg\u2014Sr based ferrite carrier and 0.5 g of a toner to be measured are put in a 30 cc glass container (inner base diameter 31 mm, height 54 mm) and the glass container is rotated with a roller-type agitator at 150 rpm for 30 minutes to frictionally charge the toner in an environment at a temperature of 23\u00b0 C. and a relative humidity of 50%; \n wherein the yellow toner, the cyan toner and the magenta toner are negatively-chargeable toners; and \n wherein, with respect to 100 parts by mass of the colored resin particles, the external additive comprises 0.1 to 1 part by mass of fine titanium oxide particles having a number average primary particle diameter of 10 to 90 nm.
