| 摘要 |
An image forming apparatus includes a rotatable image bearing member; charging means for electrically charging the image bearing member; exposure means for exposing the image bearing member charged by the charging means to light at an exposure position to form an electrostatic latent image; pre-exposure potential detecting means for detecting a potential on the image bearing member before exposure to the light, the pre-exposure potential detecting means being disposed at a position downstream of the charging means and upstream of the exposure position with respect to a rotational direction of the image bearing member; and potential adjusting means for adjusting the potential on the image bearing member before the exposure on the basis of an output of the potential detecting means, the potential adjusting means being disposed downstream of the pre-exposure potential detecting means and upstream of the exposure position with respect to the rotational direction of the image bearing member.
