ABSTRACT:
An image forming apparatus which can obtain a high-quality image although the adjustment of alignment is easy or unnecessary is provided. In the apparatus, light beams emitted from light-source means, in which a plurality of light-emitting devices are arranged in a one-dimensional direction, are focused onto a surface of a recording medium by a lens array formed by arranging a plurality of condensing lenses in a scanning direction in two lines so as to staggerly and closely place lenses in one line on lenses in another line. When the radius of a field of view of a single condensing lens is represented by X.sub.0, the diameter of the condensing lens is represented by D, and a degree of overlap is represented by m=X.sub.0 /D, the lens array is formed so as to satisfy the following condition:
