Abstract
An image forming apparatus of the type comprising a liquid crystal panel having a first substrate having first electrodes thereon, a liquid crystal layer, a second substrate having a second electrode, polarizing means and light-scattering reflection means; a light source for emitting light toward the liquid crystal from the side of the first substrate; means for forming an electrostatic light image corresponding to the light rays reflected from the liquid crystal panel; and developing means. Picture elements are arranged in a row or column with a spacing (P) between adjacent picture elements, each picture element being formed at a portion where the first and second electrodes face each other through the liquid crystal layer, the gap (P) being equal to or larger than the distance (D) from the interface between the second electrode and the liquid crystal layer to the scattering reflection surface of the light-scattering reflection means.
