| titleOfInvention | Process cartridge, electrophotographic apparatus, and image forming method |
| abstract | The present invention provides a process cartridge that has excellent image reproducibility, is less susceptible to CLN defects, and blades are less likely to be twisted. In a process cartridge, toner is toner particles containing a binder resin and iron oxide, and 1) content of carbon element present on the toner surface measured by X-ray photoelectron spectroscopy (A) The ratio (B / A) of the content (B) of the iron element to the toner is less than 0.001, 2) the projected area equivalent diameter of the toner is C, and the cross-sectional observation of the toner using a transmission electron microscope (TEM) When the minimum value of the distance between the iron oxide and the toner surface is D, the number of toners satisfying the relationship of D / C ≦ 0.02 is 50% by number or more. 3) The average circularity of the toner is 0.970. Thus, the surface layer of the electrophotographic photosensitive member contains a polycarbonate polymer having a specific structure. [Selection] Figure 1 |
