摘要： A toner container includes a container body that is used to house a toner and that is detachably attachable to a mounting portion in a developing device; and an operating member that is used to open and close a shutter. The shutter as well as the operating member includes an engaging portion that can engage with a linking member which is disposed in the mounting portion and which can perform a reciprocating linear movement. In the state in which the container body is not mounted in the mounting portion, the shutter and the operating member are in a non-linked state with each other. In contrast, in the state in which the container body is mounted in the mounting portion, the shutter and the operating member become able to be linked to each other via the linking member.

摘要： A process cartridge collectively accommodates at least a latent image carrier and a developer carrier carrying tonner for visualizing an electrostatic latent image formed on the latent image carrier and includes a side plate unit rotatably supporting the latent image carrier and the developer carrier. The side plate includes a bearing that rotatably supports a rotation shaft of the developer carrier; an elastic body that pushes the bearing against a rotation shaft of the latent image carrier; and a guiding unit that guides the bearing in a direction of the pushing. The guiding unit includes an abrasion preventing structure at a wall surface of the guiding unit that comes in contact with the bearing.

摘要： An image forming apparatus comprises a exposure device as a light source, a developer container storing developer and attached to a main body of the image forming apparatus perpendicular to a lengthwise direction of the photoconductor, a developing unit and a photoconductor unit having a photoconductor for bearing a latent image thereon each detachably attached to the main body substantially in the same direction as the developer container. An exposure device displacing mechanism displaces the exposure device between a first position enabling the exposure device to function as the light source and a second position disabling the exposure device to function as the light source. The photoconductor unit is detached when the developer container is either displaced from an initially attached position or is removed from the main body and the exposure device displacing device has displaced the exposure device to the second position.

摘要： An image forming apparatus includes an attaching and detaching unit, an attached and detached section, and a pressing member. The attaching and detaching unit includes a developing device including a developer bearer to develop a latent image on a latent image bearer and is detachably attached to the attached and detached section. The attached and detached section includes the latent image bearer, a main reference portion, and a sub-reference portion. The main reference portion contacts a main reference part of the attaching and detaching unit. The sub-reference portion contacts a sub-reference part of the attaching and detaching unit. The pressing member presses the attaching and detaching unit to generate a biasing force biasing the developer bearer toward the latent image bearer and a rotational moment toward the sub-reference portion of the attached and detached section around the main reference part with respect to the attaching and detaching unit.
