Latest Patents

Yamada's latest patents include innovative designs for process cartridges and image forming apparatuses. One notable patent describes a process cartridge that features an image holding body assembly, which includes an image holding body, a developing assembly, an urging member, a contacting and separating mechanism, and a gap forming mechanism. This design allows for the image holding body assembly to be easily inserted and removed from an assembly receiving portion. The urging member ensures that the developer holding body is pressed against the image holding body, while the contacting and separating mechanism operates to separate the two components against an urging force. Additionally, the gap forming mechanism creates a gap between the image holding body and the developer holding body, enhancing the overall functionality of the cartridge.

Another significant patent involves an image forming apparatus and transfer device that features a rotatable door. This design includes a support member with a side wall that intersects the rotation axis of a transfer roller. The support member has a hole through which a support shaft is inserted, allowing for some play. This innovative design ensures that gaps are formed between the support shaft and the wall surface of the hole during the rotation of the door, improving the device's operational efficiency.
