Abstract
An electrophotographic apparatus is provided with a self-scanning exposure device comprising a case having a shape substantially resembling the letter L, a linear light emitting head formed by linearly arranging a plurality of light emitting elements and disposed in one section of the case, and a printed wiring board having a driving circuit for driving the linear light emitting head and disposed in the other section of the case. The substantially L-shaped case containing the components of the self-scanning exposure device requires a space having a relatively small size with respect to the radial direction of photoconductive means for installation, so that the electrophotographic apparatus can be formed in a compart construction.
