| titleOfInvention | Electrophotographic developer carrier, electrophotographic developer, and method of manufacturing electrophotographic developer |
| abstract | An object of the present invention is to provide an electrophotographic developer carrier and an electrophotographic developer which have high spent resistance, little change in the amount of charge over time, and can perform high-quality electrophotographic printing for a long period of time. And a method for producing an electrophotographic developer. To solve the above-mentioned problems, a carrier for an electrophotographic developer composed of carrier particles whose surfaces are coated with a resin is observed at an accelerating voltage of 1 kV using a scanning electron microscope. In the projected image of the backscattered electrons, the total area of the high-brightness portion when binarized based on the threshold (X) set within a predetermined range is the carrier particle in the projected image of the backscattered electrons. Is defined as a high luminance area ratio (Y) in the total projection area, and a regression analysis is performed on a change in the high luminance area ratio (Y) when the threshold (X) is changed within the predetermined range using the threshold (X) as an independent variable. Is performed so that the absolute value (| a |) of the slope (a) of the obtained regression line falls within a predetermined range. [Selection diagram] None |
