Electrophotographic toner |
| abstract |
Disclosed is an electrophotographic toner, including toner particles which contain at least a binder resin and a coloring agent and have been prepared in an aqueous medium, wherein the surfaces of the toner particles are treated with an Si compound in an amount of from 0.1 to 5.0 wt % calculated as SiO 2 and with a Ti oxide in an amount of from 0.1 to 3.0 wt % calculated as TiO 2 . The toner has a dielectric loss (tan δ) of from 1×10 3 to 10×10 3 in an environment of 10° C. and 20% relative humidity (RH) and from 3×10 3 to 15×10 3 in an environment of 30° C. and 85% RH, and also has a triboelectric charge (q/m) of from 20 to 50 μC/g in an environment of 10° C. and 20% RH and from 10 to 35 μC/g in an environment of 30° C. and 85% RH. According to this configuration, electrophotographic properties are improved as represented by: a low environmental variation in chargeability; a decrease in amount of scattered toner; and less fogging. |
