Abstract
Improvements in a device for removing the electrostatic charge on a photoconductor in an image forming apparatus. The electrostatic charge-removing device has a plurality of light-emitting diodes (LEDs) incorporated in a case. The LEDs emit diffuse light to the photoconductor to remove the electrostatic charge. The LEDs are regularly spaced from each other in a orthogonal direction to a movement direction of the photoconductor in such a way that the successive diffuse light radiations emitted from the neighboring LEDs overlap with each other. The brightness is considerably higher in the locations where the diffuse light radiations overlap with each other than in the other locations. Light-blocking members are mounted upstream of their respective light radiations as viewed in the movement direction of the photoconductor, for uniforming the brightness of light in the orthogonal direction to the movement direction of the photoconductor. This evens out the image erasure line.
