Abstract
A developing device of the type developing a latent image formed on an image carrier with a two-ingredient type developer, i.e., a mixture of toner and magnetic carrier particles is disclosed. The device is operable without a sophisticated toner content control mechanism or a sophisticated developer agitating and conveying mechanism, and is capable of obviating various problems ascribable to the increase in the toner content of the developer at the opposite end portions of a developer carrier. For this purpose, the device restricts the movement of a developer present on the developer carrier in the direction substantially perpendicular to the direction in which the developer carrier conveys the developer.
