摘要： In an image forming apparatus, an object surface (14) is disposed facing one end face of a rod lens array (10), while an image surface (16) is disposed facing the other end face thereof. A lens working distance of the rod lens array on the object side is substantially equal to that on the image side. An actual object-image distance Tco is set between the conjugate length TC1 at which the average value MTFave of the MTF of the rod lens array in the lens array direction is maximized and the conjugate length TC2 at which the ΔMTF (= (MTFmax - MTFmin)/MTFave) is minimized, and a shift quantity ΔC (= |TCo - TC1|) is set within 0mm

摘要： An optical write-in head for obtaining a clear image even in printing at a relatively high recording density without generating strip-like irregularities in most cases. The optical write-in head applies light carrying image information to a photosensitive substance. The optical write-in head includes an array light source (23) having a plurality of dot light sources, each of which selectively emits the light corresponding to the image information, and a lens array (24) facing the array light source. The lens array (24) has a plurality of lens elements (25) which corresponds to the plurality of dot light sources respectively. An angular aperture θ of each of the lens elements (25) is set in a range of about 14° to 18°.
