Latest Patents
Yoshikawa's latest patents include innovative designs for developer supply containers. One of her notable inventions is a developer supply container that features a main body for containing the developer and a discharge opening for discharging the developer. This container includes a plurality of feeding projections that help feed the developer toward the discharge opening with the rotation of the main body. Each of these projections is linear and does not twist, ensuring a smooth flow of the developer.
Another significant patent involves a developer supply container that is substantially non-rotatably mountable to a developing device. This container is designed to supply developer into the developing device as the rotatable member of the image forming apparatus rotates. It includes a container body, a discharging opening for downward discharge, and a feeding portion that directs the developer toward the discharge opening. Additionally, it features a developer movement constraining portion that prevents the developer from moving in the opposite direction when the discharge opening faces upward.
