DEVELOPING DEVICE AND IMAGE FORMING APPARATUS INCLUDING SAME

摘要

A developing device of the present disclosure includes a developing roller, a toner supplying roller, a regulation blade, a casing, a toner receiver support member, a toner receiver member, and a vibration generator. The toner receiver support member is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and an image carrier. The toner receiver member is disposed along a longitudinal direction of the toner receiver support member, and has a toner receiving surface that receives toner falling from the developing roller. The vibration generator vibrates the toner receiver member. At each end part of the toner receiving surface in its longitudinal direction, there is formed a thin-walled portion that is thinner in thickness than other parts of the toner receiving surface.

主权项

1. A developing device comprising:
a developing roller that is disposed to face an image carrier on which an electrostatic latent image is formed, the developing roller being configured to supply toner to the image carrier in an opposing region where the developing roller and the image carrier face each other; a toner supplying roller that is disposed to face the developing roller, the toner supplying roller being configured to supply toner to the developing roller in an opposing region where the toner supplying roller and the developing roller face each other; a regulation blade that is disposed to face the toner supplying roller with a predetermined space therebetween; a casing that accommodates the developing roller, the toner supplying roller, and the regulation blade; a toner receiver support member that is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and the image carrier; a toner receiver member that is disposed along a longitudinal direction of the toner receiver support member, the toner receiver member having a toner receiving surface that receives toner falling from the developing roller, and a thin-walled portion that is formed at each end part of the toner receiving surface in a longitudinal direction thereof and is thinner in thickness than other parts of the toner receiving surface; and a vibration generator that vibrates the toner receiver member.
