Abstract:
1. An image forming apparatus comprising: a latent electrostatic image bearing member, and a recharging unit configured to recharge a residual toner remaining on the latent electrostatic image bearing member, wherein after transfer, the residual toner is passed through the recharging unit and is then recovered in a developing device; a charging component of the recharging unit that comes into contact with the latent electrostatic image bearing member is a polymer sheet having a surface roughness (Ra) of from 0.12 μm to 0.51 μm; the toner comprises at least a pigment, a binder resin, and a releasing agent, and contains inorganic fine particles s as an external additive, and the amount of the inorganic fine particles and the amount of the releasing agent satisfy the following Expressions 1, 2, and 3: where A is the externally added inorganic fine particle content (wt % with respect to toner), B is the adhesive strength of the inorganic fine particles (%), and X is the amount of the releasing agent (wt % with respect to toner).
