  • Publication number: 20230315005
    Abstract: An image forming apparatus includes: a main body casing having an opening; a cover movable between a closing position to close the opening and an opening position to open the opening; and a process cartridge detachably attachable to the main body casing through the opening while the cover is at the opening position. The process cartridge includes: a photosensitive drum; a developing device; a toner receiving part; and a toner conveying part. The toner receiving part has a first end portion and a second end portion. The first end portion has a receiving opening for receiving toner. When the cover is at the closing position and the process cartridge is in the attached state, the first end portion is outside the main body casing while the second end portion is inside the main body casing. The toner conveying part conveys toner in the toner receiving part to the developing device.

  • Patent number: 11720049
    Abstract: A developing cartridge includes: a developing roller rotatable about an axis extending in a first direction; a casing; a first cam and a first gear rotatable together relative to the casing about a first axis extending in the first direction; and a second cam and a second gear rotatable together relative to the casing about a second axis extending in the first direction. The second gear contacts the first gear. When the developing cartridge is attached to a drum cartridge including a photosensitive drum: at a first position of the first cam, the second cam is at a third position and the developing roller and the photosensitive drum contact each other; and at a second position of the first cam, the second cam is at a fourth position and contacts a part of the drum cartridge to move the developing cartridge to separate the developing roller from the photosensitive drum.

  • Publication number: 20230125715
    Abstract: An image forming apparatus includes a housing and a first process cartridge. The first process cartridge is attachable to and detachable from the housing. The first process cartridge includes a first photosensitive drum, a first developing roller, and a developing frame. The developing frame has a toner inlet opening. A toner cartridge has a toner supply opening. The toner cartridge is positioned above the developing frame such that the toner supply opening and the toner inlet opening face with each other in upward/downward direction. In the state where the first process cartridge to which the toner cartridge is attached is attached to the housing, the toner cartridge is incapable of being detached from the first process cartridge. In a state where the first process cartridge to which the toner cartridge is attached is detached from the housing, the toner cartridge is detachable from the first process cartridge.

  • Patent number: 10311345
    Abstract: An image-forming apparatus includes a photosensitive drum, a developing roller, a collecting roller, a belt, a cleaner, and a controller. In response to receiving a signal, the controller performs a process staring with a first process and ending with a second process. The controller rotates the developing roller at a contact position at a first speed in the first process. The controller causes the collecting roller to move residual toner to the belt to allow the cleaner to clean the belt while the developing roller is separated from the photosensitive drum in the second process. The process further includes: (a) causing the developing roller to halt rotating while maintaining the developing roller at the contact position; and (b) causing the developing roller halted in the (a) causing to start rotating at a second speed lower than the first speed while maintaining the developing roller at the contact position.
