Abstract:
An image forming device comprising:a photosensitive member;an electrostatic latent image forming unit that forms an electrostatic latent image on said photosensitive member while said photosensitive member is moving;a developing agent bearing member that bears and transports a developing agent onto said photosensitive member, said developing agent bearing member contacting said photosensitive member at a nip portion between said developing agent bearing member and said photosensitive member, said developing agent bearing member performing image development to develop at the nip portion the electrostatic latent image on said photosensitive member into a visible image using the developing agent, the developing agent being formed from a material that, when said image development is performed by said developing agent bearing member, is charged by friction at the nip portion to a greater charge amount after passing through the nip portion than before arriving at the nip portion.
