Title: Norio Takami’s Patents in Charging Technology.
Introduction
Norio Takami is an inventor associated with Mishima, Japan, and Canon Kabushiki Kaisha. His work includes inventions related to charging components and devices, with a reported portfolio of 4 patents.
Latest Patents
Two of Takami’s latest patents concern charging technology.
“Charging Device Having Rotatable Charging Roller and DC Voltage Applying Means or Source” describes a device with a rotatable elastic charging roller that contacts and electrically charges a member. Its DC voltage source controls voltage variation caused by a deformed portion of the roller, limiting the variation’s width to no more than 1%.
“Charging Member for Charging Member to Be Charged, Charging Device, and Process Cartridge” describes a conductive member coated with a layer. The patent specifies a resistance-uniformity condition: when a DC voltage between 10 and 300 volts in magnitude is applied, the ratio of the resistance standard deviation to its average value is 0.7 or less.
