Abstract
An electrostatic latent image developing device includes a rotatable developing sleeve for providing an electrostatic latent image formed on a photoreceptor with a toner so as to develop the latent image into a visual image, and a toner regulating blade which contacts at one surface with the developing sleeve so that the toner is regulated and then formed into a thin layer. The toner regulating blade has, in a surface confronting the toner bearing member, a bevelled portion which forms a wedge shaped space in a upstream side of a contact region of the blade and the developing sleeve with respect to a direction of a movement of the developing sleeve. Further, the toner regulating blade has chamfered portions in the bevelled portion at both sides thereof. Therefore, the sleeve bears a toner thin layer having a constant density.
