A toner container that can pass not only air but a toner, has toner sealing ability, and does not allow toner leakage even during transportation and an inner pressure change of the container, by placing an air permeable member at the fitting part in the casing part. An inner cap including at least the air permeable member is placed in the casing part of the inner cap, wherein the inner cap is used for a toner container that is detachably mounted to a developing unit in an image forming apparatus using an electrophotographical method, and the toner container includes at least a container main body, the inner cap, and an outer cap.

Inner cap for toner container and toner container

To provide a flange to be attached to an end of a photoconductor drum, the flange including: a drum engagement part capable of being engaged with an inner surface of the photoconductor drum; and a center hole, wherein the flange is prepared by cutting at least one of a surface of the engagement part and an inner surface of the center hole so that the axis of the center hole coincides with the axis of the photoconductor drum.

Flange, flange processing device, and method of processing flange

An electrophotographic photoreceptor including a cylindrical substrate including a photosensitive layer on an outer circumferential surface thereof and a flange adhesively fixed to at least one end of the cylindrical substrate. The flange has a joint to which a separation jig is applied to apply a tensility in a direction of separating the flange from the cylindrical substrate. A method of recycling the electrophotographic photoreceptor fills an elastic body with a fluid to inflate and contact the elastic body at the outer circumferential surface of the electrophotographic photoreceptor upon application of pressure to grasp the electrophotographic photoreceptor in the jig, and the jig is applied to the joint to pull the flange in a direction of separating the flange from the cylindrical substrate.

A package including an endless belt; a first cylindrical body contacting an inner surface of the endless belt at a first pressure; a second cylindrical body contacting another inner surface of the endless belt at a second pressure; and a third cylindrical body contacting an outer surface of the endless belt at a third pressure, wherein the endless belt is wound around the first, second and third cylindrical bodies while the first, second and third cylindrical bodies are arranged so as to be parallel to each other and substantially located in one plane, and wherein a surface of each of the first, second and third cylindrical bodies contacting the endless belt has a maximum height of from 0.8 to 150 &#x3bc;m when measured by a method based on JIS B 0601.

Package and method of forming the package

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.

A package including an endless belt; a first cylindrical body contacting an inner surface of the endless belt at a first pressure; a second cylindrical body contacting another inner surface of the endless belt at a second pressure; and a third cylindrical body contacting an outer surface of the endless belt at a third pressure, wherein the endless belt is wound around the first, second and third cylindrical bodies while the first, second and third cylindrical bodies are arranged so as to be parallel to each other and substantially located in one plane, and wherein a surface of each of the first, second and third cylindrical bodies contacting the endless belt has a maximum height of from 0.8 to 150 m when measured by a method based on JIS B 0601.

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.

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.
