Abstract
An image forming apparatus is provided which includes a development device that has no developer supply member and with which the decrease in density at a back end of a solid image and occurrence of ghosting are suppressed. A development roller having dielectric portions scattered on a surface thereof is provided and components are configured so that the position of the dielectric portions in a triboelectric series is on the same polarity side, relative to a regulating blade, as the normal charge polarity of the toner.
