A processing cartridge can be detachably installed in an electronic image forming device, where a protrusion capable of extending and retracting along a vertical direction is disposed inside the electronic image forming device. The processing cartridge includes a toner container and a waste toner container; and a movable element disposed at the lower side of the processing cartridge. The processing cartridge further includes a detachment preventing portion; the movable element is disposed with an abutting portion; and the abutting portion is capable of being abutted against the detachment preventing portion to prevent the movable element being disengaged. The processing cartridge further includes an elastic element; and the elastic element is configured to move the movable element toward the lower side of the processing cartridge.

Processing cartridge

A processing cartridge is provided. The processing cartridge can be detachably mounted in an electronic imaging device including a driving component for transmitting rotating force. The processing cartridge includes a housing and a force receiving element. The force receiving element including force receiving parts is disposed at one side of the housing and is rotatably supported by the housing. The force receiving parts are disposed at an end portion of the force receiving element along a circumferential direction of the force receiving element and protrude in a direction of a rotation axis of the force receiving element. When the processing cartridge is mounted in the electronic imaging device along a predetermined mounting direction, the force receiving parts and the driving component are engaged with each other to transmit the force.

An image forming device, a process cartridge engageable with the same and a method for firmly positioning the process cartridge in the image forming device. The image forming device includes a main frame and a main frame driving gear, wherein a guide rail is respectively arranged on left and right sides of the inside of the main frame. An installation section is arranged at a tail end of each guide rail and the installation section and guide rail respectively define a reverse hook-shape. Lugs formed at both ends of a housing of the process cartridge are driven by a radial component of driving force of the image forming device to the process cartridge to closely bear against walls of installation sections at the tail ends of the guide rails when the process cartridge is in an operating state in the image forming device.

The present invention relates to a processing cartridge, comprising a developing unit and a photosensitive unit, of which the latter consists of a photosensitive member and a developer chamber and has a developer outlet connecting the chamber and a sealing cap matching the developer outlet and used to seal the said outlet. Based on the said technical proposal, the photosensitive unit is designed with a developer outlet connecting the chamber and with a sealing cap matching the developer outlet and used to seal the said outlet, so, when the photosensitive unit becomes full with developer, the sealing cap can be opened to remove the developer in the photosensitive unit, which facilitates the cleaning without affecting the normal operation of the processing cartridge.

The invention discloses a processing cartridge, which includes a powder tube, a sliding member and a mechanism for holding the sliding member, wherein the powder tube is used for receiving toner and the sliding member is capable of freely sliding in the powder tube. The mechanism for holding the sliding member is driven to close a powder outlet under the non-use state and a powder outlet portion is arranged on the powder tube. The powder outlet is arranged on the powder outlet portion and the sliding member closes the powder outlet under the action of the mechanism for holding the sliding member under the non-use state, and moves under the action of an external force to open the powder outlet under the use state. An internal member provided with an internal powder feeding opening is also arranged inside the powder outlet portion. The internal member and the powder outlet portion form certain space so that the sliding member is capable of sliding in the space formed by the powder outlet portion and the internal member and the internal powder feeding opening of the internal member is butted with the powder outlet.

A method for controlling a distance between a photosensitive member and a developing member in an integral or separated toner cartridge. The toner cartridge is provided with an elastic member for providing an elastic force to the developing member or to the photosensitive member, so as to force the developing member to move towards the photosensitive member, or to force the photosensitive member to move towards the developing member. A production accuracy requirement of the toner cartridge is reduced by the elasticity of the elastic member. Also a device for controlling a distance between a photosensitive member and a developing member in a toner cartridge. By using the method and the device thereof, the requirement of the manufacturing accuracy of a toner cartridge can be reduced, and the negative impact of the accuracy bias caused by abrasion can be reduced, so, the product cost is saved, and the service life of the product is increased.

Method for controlling the distance between the photosensitive member and the developing member in a toner cartridge, and the device thereof

The invention relates to a toner cartridge with a locking mechanism, including a body provided with a top cover and used for receiving a developer, wherein the locking and unlocking mechanism used for locking the toner cartridge into an image forming apparatus is arranged on the body. The locking mechanism includes a handle hinged with the top cover, a gear fixedly connected with the handle, a locking lever capable of reciprocating and a torsion spring used for realizing the automatic reset of the handle. A rack engaged with the gear is arranged on the locking lever. Moreover, the handle is driven to be close to the top cover under the action of a torque force of the torsion spring under the locking state, and the gear is engaged with the rack to drive the locking lever to be extended out of the top cover so as to lock the toner cartridge. When the handle is under the unlocking state by overcoming the torque force of the torsion spring under the action of an external force, the gear and the rack are operated to drive the locking lever to be retracted into the top cover so as to unlock the toner cartridge. Unlocking and locking can be realized through a tensile force of a human hand and the reset of the torsion spring.

Toner cartridge with a lock mechanism

A processing cartridge includes at least a photosensitive drum, a developing roller, and a casing containing the photosensitive drum and the developing roller. The photosensitive drum is fixed to the casing to form an electrostatic latent image, and the developing roller develops the electrostatic latent image on the photosensitive drum. The processing cartridge also includes a handle, and the handle is retractably fixed to the casing, which has an extending status and a shrinking status opposite to the extending status.
