  • Publication number: 20250199469
    Abstract: A processing cartridge includes a photosensitive unit, including: a photosensitive drum and a photosensitive frame; a developing unit, including a developing roller and a developing frame, where the developing unit can move, relative to the photosensitive unit, between a contact position where the developing roller contacts the photosensitive drum and a separated position where the developing roller is separated from the photosensitive drum; a developing coupling, for receiving a rotational driving force and being disposed at one end of a length direction of the processing cartridge; and an elastic member, disposed between the developing unit and the photosensitive unit.

  • Publication number: 20250147463
    Abstract: A processing cartridge includes a photosensitive unit including a photosensitive component; a developing unit including a developing component, where the developing unit can move between a contact position where the developing component contacts the photosensitive component and a separated position where the developing component is separated from the photosensitive component relative to the photosensitive unit; a drum coupling for receiving a rotational driving force and transmitting the rotational driving force to the photosensitive component; a developing coupling for receiving the rotational driving force and transmitting the rotational driving force to the developing component; a force-applying component, where the force-applying component can move between an extended position where the developing component is separated from the photosensitive component and a retracted position where the developing component is in contact with the photosensitive component; and an elastic member for moving the force-applyi

  • Patent number: 11407941
    Abstract: The present disclosure provides a fluorescent nanomaterial and a preparation method and applications thereof, and the preparation method comprises: subjecting amphiphilic molecules in a solvent system to an illumination treatment and/or a heat treatment to obtain fluorescent nanomaterials. The preparation of fluorescent nanomaterials provided by the present disclosure is simple in process, simple and easily available in raw materials and requires neither additional addition of a strong acid, a strong alkali, a passivating agent and the like, nor high temperature and high pressure in the preparation process. The whole process is environmentally friendly and pollution-free and the products can be used in various fields.

  • Patent number: 11104589
    Abstract: The present disclosure provides a recycling method of amphiphilic surface-active pollutants in water, comprising: performing a polymerization reaction by illumination treatment on the amphiphilic surface-active pollutants in water to form a polymerization product; performing self-assembly on the polymerization product for aggregation to form a fluorescent material, and performing separation to obtain a recycled product. Through treatment of the amphiphilic surface-active pollutants by illumination, the present disclosure can realize the recycled utilization of the amphiphilic pollutants in the wastewater by one step of reaction, so that the amphiphilic surface-active pollutants can be converted into usable fluorescent materials, and the biological toxicity is greatly reduced.
