Abstract: A detachable container includes: a container body; and operation units on both sides of the container body attaching and detaching the container body. Each operation unit includes an outer gripping unit at an outer side of a respective one of both side walls of the container body, an inner gripping unit at an inner side of the respective one of both side walls of the container body in the width direction in an attachment and detachment operation side surface of the container body, and a cover projecting in an eave shape laterally from a respective one of both sides of the attachment and detachment operation side surface of the container body in the width direction, the cover covering the gap between the respective one of both side walls of the container body and a projecting end of the outer gripping unit when viewed from the attachment and detachment operation side.

Abstract: An image forming apparatus includes an image carrier, a developing roller, a biasing member, and a fluctuation preventing member. A latent image is formed on the image carrier. The developing roller is provided to face the image carrier and develops the latent image on the image carrier. The biasing member is provided on an outside of an end portion of the developing roller and biases the image carrier and the developing roller in a direction where the image carrier and the developing roller approach each other. The fluctuation preventing member is interposed between the image carrier and the developing roller and prevents, along with the biasing member, a fluctuation in a distance between a surface of the developing roller and a surface of the image carrier in a region where the image carrier and the developing roller face each other.

Abstract: A developer carrier includes a transmitting member that is rotatable and transmits a driving force; and a developer carrying member that carries developer and is provided coaxially with the transmitting member, the developer carrying member being rotatable when receiving the driving force from the transmitting member, the developer carrying member being displaceable with respect to the transmitting member in an intersecting direction that intersects an axial direction of the transmitting member.

Abstract: Provided is an image forming apparatus including an image carrier on which a latent image is developed, a developing roller that is provided to face the image carrier to perform development for the latent image of the image carrier, an urging unit that urges the image carrier and the developing roller so that the image carrier and the developing roller approach each other, and a distance regulating unit that includes a viscoelastic body that is deformed according to a change of a distance between the image carrier and the developing roller, and regulates at least one of a maximum value of the distance between the image carrier and the developing roller and a minimum value of the distance between the image carrier and the developing roller so that the distance between the image carrier and the developing roller falls within a predetermined range.
