摘要： A powder container is for use with an image forming apparatus, and the image forming apparatus includes a driving protrusion that is rotatable and that protrudes toward an upstream side in an insertion direction in which the powder container is inserted. The powder container includes a container body to store powder, a cap attached to the container body, and a transmitted structure provided on the cap to contact the driving protrusion. The transmitted structure extends outward from an outer circumference of the powder container. The cap is rotatable relative to the container body in a predetermined angular range. The rotation of the cap relative to the container body is restricted so that the container body rotates along with the rotation of the cap when the rotation of the cap exceeds the predetermined angular range.

摘要： A powder container is insertable in an image forming apparatus, and includes a main-body interlocking portion that is rotatable and protrudes toward an upstream side in an insertion direction in which the powder container is inserted, the image forming apparatus including an identifier protrusion that protrudes toward the upstream side in the insertion direction to identify a type of the powder container. The powder container includes a container interlocking portion configured to interlock with the main-body interlocking portion; and an interlocked portion configured to interlock with the identifier protrusion. The interlocked portion is provided in a front end of the powder container in the insertion direction. The container interlocking portion stands outward from an outer circumference of the powder container. The container interlocking portion and the interlocked portion are rotated integrally.

摘要： A powder container is insertable in an image forming apparatus. The powder container includes a plurality of transmitted surfaces, at least one of the transmitted surfaces being configured to contact a first protrusion of the linage forming apparatus, the first protrusion being rotatable and protruding toward an upstream side in an insertion direction in which the powder container is inserted. The transmitted surfaces stand outward from an outer circumference of the powder container so that one of the transmitted surfaces is connected to another transmitted surface adjacent to the one of the transmitted surfaces by an inclined surface.

摘要： An image forming apparatus includes a plurality of developer containers to contain different types of developers and a container mount in which the plurality of developer containers is removably installed and arranged adjacent to each other. Each of the developer containers includes an engagement portion. The engagement portion of one of the developer containers engages the engagement portion of another of the developer containers adjacent to the one of the developer containers when the developer containers are installed in the container mount in a predetermined order, to allow the developer containers to be installed. Further, the engagement portion of one of the developer containers interferes with the engagement portion of another of the developer containers adjacent to the one of the developer containers when the developer containers are installed in the container mount in a different order from the predetermined order, to prevent the developer containers from being installed.

摘要： A cleaning unit includes a first blade and a second blade. The first blade is in contact with an image carrier or a paper carrier and removes adhered substances remained on surface of these. The second blade has an abrasive layer that is formed by including abrasive particles in an elastic material and is disposed in the downstream side of the first blade. The second blade is allowed to be in contact with the image carrier 1 or the paper carrier. Volume occupancy of abrasive particles in an area of contact of the second blade with either the image carrier or the paper carrier is not less than 50 percent and not more than 90 percent.

摘要： In an image forming apparatus, an area applied with a lubricant, i.e., an area of a lubricant layer having a uniform thickness, is obtained by spreading the lubricant by a lubricant smoothing blade. The area applied with a lubricant covers an area cleaned by a cleaning blade, i.e., a contact portion of the cleaning blade with a photoconductor.
