Latest Patents

Ichikawa's recent innovations include two significant patents that focus on improving toner cartridge performance. The first, titled "Toner cartridge with differential member and image forming apparatus," addresses the issue of rotation torque during startup, particularly when toner solidifies. This inventive toner cartridge features a toner stirring member with a rotating shaft and stirring blade, alongside a toner discharge member that includes a spiral-shaped conveyance blade. The design integrates a second gear with a bearing projection that abuts an abutment member during the second gear's rotation, efficiently transmitting motion through first and third gears to the conveyance shaft. Additionally, a rotationally driving section imparts necessary rotary force to the second gear, ensuring smooth operation.

The second patent, titled "Toner supply device and image forming apparatus," involves a rotary-type toner supply device that features a uniquely designed toner container. The container has a peripheral wall shaped to enclose a side face of an imaginary column and includes a toner discharge port. Inside the container, a scraping member rotates freely around a central axis, equipped with curved parts that follow the spiral form along the column's side, effectively ensuring consistent toner supply.
