    摘要: An image forming apparatus including an image bearer, a magnetic field generator, a two-component developer bearer, a developing electric field generator, and an image developer. The two-component developer has at least a current speed index (25FRI) of from 0 to 2.0, which is determined by the following formula: 25FRI=(total energy at 10 mm/s/total energy at 100 mm/s). The total energy is an integral sum of a rotary torque and a vertical load when a blade of a powder fluidity analyzer spirally rotates at 10 mm/s and 100 mm/s, respectively, in the developer having a volume of 25 ml after idly agitated in the image developer for 10 minutes.

    摘要: An external additives for electrophtographic toner comprising finely divided oxide particulate including a silicon compound and a compound for doping said oxide particulate, wherein particle diameter of the primary particle of said finely divided oxide particulate is in the range of 30 nm to 150 nm, and the primary particle of said finely divided oxide particles is substantially spherical shape having the roundness in the range of 0.95 to 0.996, is provided. And this external additives is capable of evading from the embedding of external additives into toner even if after the toner is held in the storage under the condition of high temperature and high humidity, thereby the additives is capable of showing sufficient functions as fluidizing agent and charge supplement agent, and is capable of inhibiting an abnormal charge elevation even after being stored under the low temperature and low humidity.
