Abstract: A developer container includes a containing portion that is capable of containing a developer therein, the containing portion having an opening through which the developer passes; a first opening/closing member that is movable between a first open position at which the opening is open and a first closed position at which the first opening/closing member closes the opening; and a second opening/closing member that is movable between a second closed position at which the second opening/closing member doubly closes the opening by covering an outside of the first opening/closing member and a second open position at which the first opening/closing member is exposed to the outside, wherein a direction in which the second opening/closing member moves between the second open position and the second closed position is different from a direction in which the first opening/closing member moves between the first open position and the first closed position.

Abstract: A powder container includes a containing portion that is capable of containing powder therein, the containing portion having an opening through which the powder passes; an opening/closing member that is supported by the containing portion so as to be movable between an open position at which the opening is open and a closed position at which the opening/closing member closes the opening; and an engaged portion disposed on a side surface of the opening/closing member with respect to an installation direction, the installation direction being a direction in which the containing portion is removably installed into an apparatus, the engaged portion restraining a movement of the opening/closing member by being engaged with an engaging portion of the apparatus when the containing portion is installed in the apparatus.

Abstract: An image forming apparatus includes: an image carrier; a latent-image forming device; a developing device; a latent-image forming device contacting/separating mechanism; and a developing device contacting/separating mechanism, and the latent-image forming device contacting/separating mechanism allows the latent-image forming device to be movable to the latent-image forming device contacting position in a state where the developing device is moved to the developing device contacting position.

Abstract: A developer container is provided with a container body. An opening is formed through the container body. An opening/closing lid closes the opening. A lid holding frame holds the opening/closing lid in such a manner that the opening/closing lid can move between an open position and a closed position. A stopper stops the opening/closing lid and thereby preventing it from moving toward the open position in a state that the opening/closing lid is located at the closed position. A contact portion comes into contact with a hook portion provided in a container receiving portion when the developer container is inserted into the container receiving portion. A deformable portion deforms the stopper to such an extent that the stopping of the opening/closing lid by the stopper is canceled when the developer container is inserted into the container receiving portion and the contact portion comes into contact with the hook portion.

Abstract: An image forming apparatus includes: an image carrier; a latent-image forming device; a developing device; a latent-image forming device contacting/separating mechanism; and a developing device contacting/separating mechanism, and the latent-image forming device contacting/separating mechanism allows the latent-image forming device to be movable to the latent-image forming device contacting position in a state where the developing device is moved to the developing device contacting position.

Abstract: A powder storage container includes a container body, an opening formed in a portion of the container body, an opening-and-closing cover, a cover holding frame, a protrusion portion provided in the opening-and-closing cover, a blocking portion provided in the cover holding frame, a position regulating protrusion protruding from the cover holding frame, and a disengagement suppressing protrusion provided in the opening-and-closing cover. When the opening-and-closing cover takes such an attitude that the opening-and-closing cover is swingably supported by a contact portion, serving as a fulcrum, between the disengagement suppressing protrusion and the cover holding frame and is arranged along the opening-and-closing operation direction, a distal end position of the protrusion portion is located in a position where the distal end position can be released from the blocking portion.

Abstract: The image forming apparatus is provided with: an image carrier; an exposure member that exposes the image carrier and forms an electrostatic latent image on the image carrier; a developing member that develops the electrostatic latent image formed on the image carrier; and a contact-retracting unit that rotates the developing member taking a predetermined position as the rotational center, and brings the developing member in contact with or proximity to the image carrier or retracts the developing member from the image carrier.

Abstract: There is provided a development apparatus including: a first developer storage container and a second developer storage container that store developer, having a first a and second openings, respectively; a first transport member provided within the first developer storage container, and that causes the developer to move to the second developer storage container via the first opening; a second transport member provided within the second developer storage container, and that causes the developer to move to the first developer storage container via the second opening; a developer holding member that performs development by causing the developer to move to a position facing an image holding body on which a latent image is formed; and a moving member provided so as to fit between an inner wall face of the second developer storage container and an outer edge of the second transport member.
