    摘要： A toner comprising: a plurality of mother particles; and a plurality of external additive particles to be attached to the mother particles, the external additive particles including external additive particles attached to the mother particle and external additive particles liberated from the mother particles, wherein an inclination (particle sizes of the external additives/particle sizes of the mother particles) of an approximation straight line obtained by approximating distribution of particle sizes of the external additives with respect to the particle sizes of the mother particles by a least-square method is not larger than 0.6. Also, disclosed is an image forming apparatus using the toner.

    摘要： An image forming apparatus for forming an image on both of a first side and a second side which are the right side and the back side of recording material, which comprises an image carrier on the surface of which a toner image is formed, a transfer member for forming a transfer part between the transfer member and the image carrier to transfer the toner image on the image carrier onto the recording material, a transfer voltage applying section for applying transfer voltage to the transfer member, a fixing member for heating the recording material, on which the toner image is transferred by the transfer member, passed therethrough to fix the toner image on the recording material, a reversing path for reversing the two sides of the recording material passed through the fixing member and returning the reversed recording material to the transfer part again, a timer section for measuring elapsed time since the recording material, on the first side of which a toner image is transferred, passes through the fixing member until the transfer of a toner image on the second side is started when an image is formed on the first and second sides of the recording material, a humidity detecting section for detecting humidity, and a control section for selecting transfer voltage for transferring a toner image on the second side of the recording material based upon elapsed time measured by the timer section and humidity detected by the humidity detecting section.
