Abstract

In an image forming apparatus of the present invention, a plurality of writing electrodes are supported by an elastic and flexible substrate such that the writing electrodes are aligned in a plurality of rows each extending in the axial direction of the latent image carrier (in the main scanning direction). The writing electrodes are each formed in, for example, a triangle and alternately inverted. In this case, one end of a writing electrode is overlapped with a next writing electrode, as seen in the direction perpendicular to the axial direction of the latent image carrier (the rotational direction of the latent image carrier; the feeding direction). Therefore, this design prevents occurrence of image defect due to linear stains and allows foreign matters adhering to the surface of the latent image carrier to pass through spaces between the adjacent writing electrodes.
