    摘要： An image forming apparatus and a process cartridge have high-durability and stably form high quality images under long-term use without reducing image density even when concentration of discharge products at the surface of an electrophotographic photoconductor becomes uneven in a discharge region of a charging unit. The apparatus employs an image forming method and has a corona discharge type charging unit discharging in a non-contact manner, the photoconductor placed to face the charging unit and the outermost surface layer thereof contains a filler and an amine compound with a specific structure, and an airflow adjusting device which carries air taken from the outside of the apparatus to the vicinity of the charging unit or the photoconductor so that ozone concentration and unevenness thereof are maintained at an average of 30 ppm or less and 15 ppm or less respectively at the surface of the photoconductor in the discharge region.
