Latest Patents
One of Kaneko's latest patents is for an electrophotographic toner and image-forming system. This toner contains a fixing resin, a colorant, and wax. The wax includes hydrocarbon wax with a number-average molecular weight not exceeding 600, and polyethylene wax with similar molecular weight restrictions. The toner is designed to have a melting viscosity of less than 15 mPa·s at 140°C and a crystallinity of less than 95%. Additionally, the ratio of hydrocarbon wax to polyethylene wax ranges from 1:10 to 2:1. The maximum absorption peaks in the heat-up time absorption calorie curve of the toner, measured by a differential scanning calorimeter, occur at a temperature not exceeding 75°C, with an onset temperature for heat absorption not higher than 65°C.
Another significant patent by Kaneko is for an electrostatic image developing toner and image forming method. This toner includes a fixing resin and hydrocarbon-based wax. The wax consists of first and second wax components, with specific ratios and properties regarding molecular weight, melt viscosity, and degree of crystallinity. The first wax has a weight average molecular weight to number average molecular weight ratio greater than 1.5, while the second wax maintains a ratio not exceeding 1.5.
