ABSTRACT:
A process cartridge detachably mountable relative to a main assembly of an electrophotographic image forming apparatus, includes an electrophotographic photosensitive member; a developing device for developing a latent image formed on the electrophotographic photosensitive member; a toner accommodating portion for accommodating toner to be used by the developing device to develop the latent image; a first toner feeding member for feeding the toner accommodated in the toner accommodating portion toward the developing device; a second toner feeding member for feeding the toner accommodated in the toner accommodating portion toward the developing device; wherein the second toner feeding member starts to operate in response to detection of decrease of a remaining amount of the toner accommodated in the toner accommodating portion to feed the toner accommodated in the toner accommodating portion toward the developing device.
