| abstract | [PROBLEMS] To suppress white background stains, afterimages, scattering, streaks, blurring, and missing dots due to toner particle size distribution and matching between toner and photoconductor, with good image quality, fine line reproducibility, and cleanability, and high-speed printing. An image forming apparatus and a cartridge capable of stably forming a high-resolution image by preventing smearing and selective development during long-term use. A photosensitive layer of an electrophotographic photosensitive member has main diffraction peaks at Bragg angles (2θ) of 9.0 ° and 27.2 ° with respect to CuKα rays, and falls within a range of 9.3 ° to 9.8 °. An image forming apparatus comprising oxytitanium phthalocyanine having at least one main diffraction peak, wherein the toner satisfies all of the following requirements. (1) Volume median diameter (Dv50) is 4.0 μm or more and 7.0 μm or less (2) Average circularity is 0.93 or more (3) Volume median diameter (Dv50) and 2.00 μm or more and 3.56 μm or less The relationship of the toner number% (Dns) satisfies Dns ≦ 0.233EXP (17.3 / Dv50). |
