摘要： The present invention provides an image forming apparatus which can exhibit an excellent charge eliminating effect by erasing a transfer memory using a precharging means with optimized conditions even when a positively-charged single-layer-type electrophotographic photoconductor is used as a photoconductor. In the image forming apparatus which sequentially arranges a charging means, a developing means, a transfer means, and a charge eliminating means around a single-layer-type electrophotographic photoconductor, the charging means charges a surface of the single-layer-type electrophotographic photoconductor with a positive polarity, a precharging means having a conductive member is arranged on an upstream side of the charge eliminating means, the conductive member is brought into contact with the electrophotographic photoconductor, and a current density Ib(μA/m2) of the injected current into the photoconductor from the conductive member is set to a value of 700(μA/m2) or more.
