Tsunemitsu Fukami is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of image forming technology, holding a total of 8 patents. His innovative designs and methods have advanced the capabilities of image forming apparatuses, making them more efficient and effective.

Latest Patents

Fukami's latest patents include an image forming apparatus and an image forming method. The image forming apparatus features a photosensitive member, a charger, a developing device, a transfer device, and a controller. In the printing control, the controller rotates the photosensitive member in a forward direction and applies a first transfer bias. In a reverse rotation control, the controller rotates the photosensitive member in a reverse direction and applies a second transfer bias that is zero after finishing the printing control. Additionally, in a forward rotation control, the controller applies a third transfer bias for a period that includes the time a part of the photosensitive member reaches the transfer device after finishing the reverse rotation control. The third transfer bias has an opposite polarity to the first transfer bias and an absolute value larger than the second transfer bias.

Another notable patent is an image forming apparatus that includes a first image forming unit with a first transfer unit forming a first nip with a first photosensitive drum for black, and a second image forming unit with a second transfer unit forming a second nip with a second photosensitive drum for color. The control device is designed to supply a first transfer current for a first time period during which the first sheet or the second sheet passes through the second nip, and a second transfer current, which is smaller than the first transfer current, for a second time period that is a sheet interval between the first sheet and the second sheet.
