Abstract
The object is to provide a toner which can be smoothly replenished by a toner replenishing device using a powder pump even when the toner contains a releasing agent, and an image forming apparatus using the toner. There is provided a toner, which comprises a binder resin, a colorant and a releasing agent, has a dynamic friction coefficient of 0.15 to 0.35, and is replenished by the toner replenishing device having a powder pump configured to automatically supply the toner and a toner container arranged in conjunction with the powder pump so as to develop a latent electrostatic image on a image bearing member.
