Abstract: A hollow, cylindrical toner bottle of the present invention discharges toner stored therein when mounted to an electrophotographic image forming apparatus in a substantially horizontal position and then rotated about its axis. The toner bottle is made up of a mouth including a toner outlet and a cylindrical wall, and a body including a circumferential wall and a bottom. The mouth is formed by injection molding. The outer circumference of the toner outlet has circularity of 0.7 mm or below.

Abstract: In an image forming apparatus, a toner container removably set on the apparatus and a developing section included in the apparatus are communicated to each other by a delivery passage. Toner can be delivered from the toner container to the developing section via the delivery passage by a stream of air even when the container and developing section are located at remote positions. An elongated member located on the image forming apparatus extends into the toner container outlet and a mating portion forms a sealing enclosure between the toner container outlet and the elongated member. A tight contact enhancing member may be provided to enhance the contact of the sealing enclosure. The toner container may be a sack formed of flexible material.
