An image process cartridge at least having a latent-image-bearing member for bearing electrostatic latent image, a developing means using nonmagnetic mono compent developer to visualize electrostatic latent image beared on the latent-image-bearing member and form toner images is provided. The developing means comprising: a developer-holding part and a developing member, a developer agitation and transport member, a developing member compression joined with the latent-image-bearing member, a confining member for confining amount of developer. A vertical section which bisects in the process cartridge the surface of the latent-image-bearing member with which surface the developing member is brought into pressure contact, a developer agitation and transport member has at least two rotary agitation and transport means having rotating shafts falling at right angles with the vertical section. |
