Image forming apparatus and process cartridge |
| abstract |
An image forming apparatus includes an image holding member including a conductive substrate, a photosensitive layer, and a protection layer; a charging unit; an electrostatic image forming unit; a developing unit that includes an electrostatic image developer having a toner and develops the electrostatic image to form a toner image; a transfer unit that transfers the toner image onto a surface of a recording medium; a fixing unit that fixes the toner image; and a cleaning unit that includes a cleaning blade. The toner includes toner particles and silica particles having a number average particle size of 110 nm to 130 nm, a large-diameter-side number particle size distribution index (upper GSDp) of less than 1.080, and an average circularity of 0.94 to 0.98, wherein 80 number % or more of the silica particles have a circularity of 0.92 or more. |
