PROBLEM TO BE SOLVED: To provide an image forming apparatus in which a residual toner remaining on a latent electrostatic image bearing member is recovered and reused, the contamination of a charging member to charge the latent electrostatic image bearing member is prevented, the recovery of the residual toner at a development step is facilitated, and superior image stability is ensured, and to provide a toner, a toner container and a process cartridge. SOLUTION: In the image forming apparatus in which the residual toner remaining on a surface of the latent electrostatic image bearing member, after transfer is passed from the latent electrostatic image bearing member through a charging component of the subsequent recharging unit for recharging and is then recovered in a developing device; the charging component is a polymer sheet having a surface roughness (Ra) of 0.12-0.51μm; the toner contains at least a pigment, a binder resin and a releasing agent, and contains inorganic fine particles as external additives, and the amount of the inorganic fine particles and the amount of the releasing agent satisfy equations (1), (2) and (3), where A is the content of the externally added inorganic fine particles; B is the bond strength of the inorganic fine particles; and X is the amount of the releasing agent. Expressions (1), (2), (3) are respectively: [A×(100-B)]×X<530 [A×(100-B)]>60, and X>2.5. COPYRIGHT: (C)2009,JPO&INPIT
