Image forming apparatus and cartridge |
| abstract |
Provided are an image forming apparatus and a cartridge which are excellent in image stability with no smear when used for a long period of time even when a high-speed printing machine is used. . An image forming apparatus or cartridge comprising an electrophotographic photosensitive member and a toner, wherein the photosensitive layer of the photosensitive member contains a polycarbonate resin or a polyarylate resin having a specific structure, and the toner satisfies all of the following requirements: An image forming apparatus or cartridge which is toner satisfying the above. (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 particle diameter of 2.00 μm or more 3 The relationship of the number% (Dns) of toner of .56 μm or less is as follows: Dns ≦ 0.233EXP (17.3 / Dv50) (4) The number variation coefficient is 24.0% or less. |
