20150117879 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a body of the image forming apparatus; and a cartridge installable with respect to the body, wherein the cartridge includes a developer accommodating portion accommodating a developer; a developing portion supporting a developer holding member holding the developer thereon; and a shutter configured to be movable between an open position at which the shutter opens a communication port and a close position at which the shutter closes the communication port. The body includes a detecting section detecting a state of the cartridge which changes as the cartridge is used, and a judging section judging whether or not a cartridge exchange timing for exchanging the cartridge has arrived, based on the state of the cartridge detected by the detecting section; and the shutter moves to the close position under a condition that the judging section judges that the cartridge exchange timing has arrived. | 04-30-2015 |
20150117907 | CARTRIDGE AND LID MEMBER FOR CARTRIDGE - There is provided a cartridge, including: a casing including an inlet portion configured to be filled with a developer; and a lid member configured to close the inlet portion by being installed to the inlet portion from an installation direction, wherein the casing includes a first protruding portion which projects inward beyond an inner surface of the inlet portion in a direction perpendicular to the installation direction; and the lid member includes a recessed portion which is recessed from an outer surface of the lid member in the direction perpendicular to the installation direction and is configured to be engaged with the first protruding portion in a case that the lid member is installed to the inlet portion. | 04-30-2015 |
20150125175 | Developing Cartridge Having Electrode - A developing cartridge includes a casing, a developer-carrying member, a supply member, a developing electrode, a supply electrode, and an insulating member. The casing is configured to accommodate therein developer. The developer-carrying member is configured to rotate about a rotational axis and carry the developer thereon. The supply member is configured to supply the developer to the developer-carrying member. The developing electrode is configured to be electrically connected to the developer-carrying member. The supply electrode is configured to be electrically connected to the supply member. The insulating member insulates the developing electrode and the supply electrode with each other. The developing electrode, the insulating member, and the supply electrode are overlapped in this order in an axial direction of the rotational axis. | 05-07-2015 |
20150125176 | Developing Cartridge Having Electrode - The developing cartridge includes a casing, a rotating member, and an electrode. The casing may be configured to accommodate therein developer. The rotating member has a rotational shaft extends in an axial direction. The rotating member is configured to rotate about the rotational shaft and carries the developer thereon. The electrode member is configured to be electrically connected to the rotating member. The electrode member covers at least part of the rotational shaft from an orthogonal direction orthogonal to the axial direction and is arranged to confront the casing in the axial direction. The electrode member is configured to move in the orthogonal direction in accordance with a movement in the axial direction. | 05-07-2015 |
20150205254 | Image-Forming Device And Cartridge Mountable In The Same - An image-forming device includes a cartridge and a main body including a cartridge receiving section configured to receive the cartridge. The cartridge includes a first cartridge configured to store developer therein, and a second cartridge configured to detachably accommodate the first cartridge. The first cartridge is attachable to the second cartridge in a state where the second cartridge alone is mounted in the cartridge receiving section, the first cartridge being configured to be restricted from getting detached from the second cartridge in a state where the first cartridge and the second cartridge are both mounted in the cartridge receiving section. | 07-23-2015 |
20150205255 | Cartridge Provided with Protection Cover Capable of Protecting Developer Carrier and Image Forming Apparatus Provided with the Same - A cartridge includes: a first cartridge; a second cartridge; and a protection cover. The first cartridge includes: a photosensitive body; a photosensitive-body accommodating portion for accommodating the photosensitive body; and a cartridge mounting portion. The second cartridge is detachably mounted in the first cartridge and includes a developer carrier. The protection cover provides an attached state to be attached to the second cartridge and a detached state to be detached from the second cartridge. The protection cover at the attached state faces the developer carrier to protect the developer carrier. The second cartridge provides an accommodated position to be accommodated in the cartridge mounting portion when the protection cover is at the attached state, and a mounted position to be mounted in the cartridge mounting portion when the protection cover is at the detached state. | 07-23-2015 |
