摘要:
The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.

A developer container includes a container body in which a developer containing chamber and a discharge outlet are formed, a developer conveyance member disposed inside the developer containing chamber and including a first conveyance portion and a second conveyance portion downstream from the first conveyance portion in a developer conveyance director, a canopy disposed inside the container body and facing the discharge outlet, a developer conveyance chamber defined by the canopy and an inner face of the container body in which the discharge outlet is formed, and a return opening formed in the canopy downstream from the discharge outlet. A developer conveyance velocity (Q2) of the second conveyance portion of the developer conveyance member to transports the developer toward the return opening is slower than a developer conveyance velocity (Q1) of the first conveyance portion of the developer conveyance member.

An image forming apparatus includes an image bearer, an optical writing unit to writing an electrostatic latent image on the image bearer, the optical writing unit including multiple optical writing elements arranged in a longitudinal direction of the image bearer and a frame to hold the multiple optical writing elements, a development device to develop the electrostatic latent image on the image bearer with developer, a developer container for containing the developer supplied to the development device, and a developer amount detector to detect an amount of developer contained in the developer container based on a light transmission amount between a light-emitting element and a light-receiving element. At least one of the light-emitting element and the light-receiving element of the developer amount detector is attached to the optical writing unit.

A powder container is provided. The powder container includes a powder storage and a conveyer. The powder storage stores a powder to be used for image formation and has a vent hole to pass air between an inside and an outside of the powder storage. The conveyer conveys the powder inside the powder storage. The vent hole is on an upper surface of the powder storage facing the conveyer.

An image forming apparatus includes an apparatus body, an apparatus-side terminal provided to a first inner side wall of the apparatus body, a developer container to contain developer and to be removably installable in the apparatus body, a container-side terminal electrically connectable to the apparatus-side terminal and disposed in a first end portion of the developer container in a longitudinal direction thereof, and an apparatus-side protrusion projecting inward from the first inner side wall of the apparatus body. In removal of the developer container from the apparatus body, a second end portion of the developer container in the longitudinal direction is disengaged from the apparatus body before the first end portion is disengaged from the apparatus body, and the apparatus-side protrusion contacts the first end portion of the developer container immediately after removal of the developer container from the apparatus body is started.

A development device includes a housing for containing developer, a developer bearer to carry by rotation the developer contained in the housing to a development range position facing a latent image bearer, and developer conveyance device that includes a rotary shaft, a conveyance blade extending axially along the rotary shaft, projecting from the rotary shaft, and extending obliquely to the rotary shaft, to transport developer as the rotary shaft rotates, and a flexible agitation blade provided to the rotary shaft. An axial range of the flexible agitation blade overlaps at least partially with that of the conveyance blade. The flexible agitation blade has a width wider than a width of the conveyance blade and extends beyond an outer edge of the conveyance blade in the direction of diameter of the rotary shaft.
