发明名称 Image forming apparatus adopting image bearing member cleaner-less system
摘要 A image forming apparatus includes an image bearing member to be moved rotationally, charging means for electrically charging the image bearing member and toner remaining on the image bearing member, electrostatic latent image forming means for forming an electrostatic latent image on the image bearing member charged by the charging means, developing means for visualizing the electrostatic latent image while recovering the toner remaining on the image bearing member, toner charging means which is disposed upstream from the charging means in a rotational direction of the image bearing member and is to be supplied with a voltage of a polarity identical to that of a voltage to be applied to the charging means to electrically charge the toner remaining on the image bearing member, recording means for recording an operation history of the image forming apparatus, and control means for controlling the voltage to be supplied to the toner charging means on the basis of the operation history of the image forming apparatus recorded by the recording means.
