ELECTROPHOTOGRAPHIC TONER AND METHOD FOR MANUFACTURING THE SAME, ELECTROPHOTOGRAPHIC DEVELOPER, TONER CARTRIDGE, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide an electrophotographic toner forming high-quality images for a long period of time, and a method for manufacturing the toner, and to provide an electrophotographic developer, a toner cartridge, a process cartridge, and an image forming apparatus. PSOLUTION: The electrophotographic toner includes a binder resin and a colorant. When a total intensity (kcps) of all elements detected in the toner due to fluorescent X-ray measurement is denoted by A and an intensity of nitrogen is denoted by B, B/A ranges from 0.01 to 0.5, and a ratio of nitrogen measured by X-ray photoelectron spectrometry after ion etching at an accelerating voltage at 10 mV for 180 seconds ranges from 0.1 atom% to 7.5 atom%. The present invention discloses a method for manufacturing the toner, an electrophotographic developer, a toner cartridge, a process cartridge, and an image forming apparatus.
