Latest Patents

Sano's latest patents include a two-component development apparatus and a process cartridge. The two-component developing apparatus features a developer carrier, a first regulating member, a developer container, and a toner container. This innovative design allows for efficient carrying and transferring of a two-component developer that includes a magnetic carrier. The first regulating member effectively regulates the amount of developer carried by the developer carrier. Additionally, the developer container receives the developer removed by the first regulating member, while the toner container supplies toner to the developer carrier. The developer stirring member is designed to carry and stir the developer between the first and second regulating members, ensuring optimal performance.

Another notable patent is the developing device using a two-ingredient type developer and an image forming apparatus that includes the same. This developing device contains magnetic toner grains and features a main pole for development disposed in a sleeve. The flux density generated by the magnetic pole is designed to achieve an attenuation ratio of 50% or above. The toner grains have a weight mean grain size of 6.0 µm to 8.0 µm, with smaller grains occupying 40% to 80% of the entire developer. This innovative design reduces toner scattering and image defects, enabling ultrahigh resolution in imaging.
