Patent ID: 8139989

Claim:
A toner bottle for containing toner to be supplied to a developing section for developing an electrostatic latent image on a surface of a photoreceptor, comprising: a bottle main body in a cylindrical shape for supplying toner contained therein to the developing section by rotation of the bottle main body; and a rubbing member disposed inside the bottle main body for rubbing an inner wall surface of the bottle main body by rotation of the bottle main body, wherein the bottle main body has: a toner opening which serves as an outlet for supplying toner to the developing section; and one or more ribs protruding from the inner wall surface of the bottle main body and formed in a discrete manner, for guiding and transporting toner to the toner opening by rotation of the bottle main body, wherein the rubbing member has: a shaft section disposed over a whole area in a direction in which an axis of rotation of the bottle main body extends; and a rubbing section having one end supported by the shaft section and another end formed so as to be in contact with the inner wall surface of the bottle main body, wherein the shaft section has an inclined support section, a longitudinal axis of the inclined support section extending at a predetermined angle with respect to the axis of rotation of the bottle main body, and wherein the rubbing section is supported by the inclined support section so as to extend in a direction perpendicular to the longitudinal axis of the inclined support section.
