Abstract
The present invention relates to a mono-component developing device, which develops an electrostatic latent image formed on an electrostatic latent image-supporting member with a toner having a weight-average particle size of from 4 to 10 &mgr;m, a compression rate of not more than 32% and an angle of repose of not more than 38°, and a toner used for the mono-component developing device. Even in the case when a comparatively great stress is imposed on the toner particles, the toner of the present invention maintains superior fluidity and makes it possible to provide a high-quality image.
