IMAGE FORMING APPARATUS WHICH USES ELECTROSTATIC LATENT IMAGE FOR COLOR MISREGISTRATION CORRECTION |
摘要 |
An image forming apparatus includes a control unit configured to form electrostatic latent images for correction on a photosensitive member a voltage application unit configured to apply a voltage to a process unit; a current detection unit configured to detect a current to the voltage application unit via the process unit when the voltage is applied to the process unit; and a conversion unit configured to convert an output value detected by the current detection unit such that a variation range of the output value detected by the current detection unit at a formation period of the electrostatic latent image for correction becomes larger than a variation range of the output value detected by the current detection unit at a one-rotation period of the photosensitive member on which the electrostatic latent image is not formed. |
