ABSTRACT:
An image forming device is improved in that crosstalk between adjacent lenses is decreased thereby to improve an imaging power. In the image forming device a lens array has a plurality of lenses continuously formed. A roof prism array is also provided therein with a plurality of roof prisms respectively having a rectangular reflection plane and arranged at the same pitch as that of the lenses in the lens array. The lens array and the roof prism array are integrally formed of a plastic. A space portion, which is a portion unfilled with a resin, is formed between respective two adjacent roof prism lens pairs to prevent the crosstalk therebetween. Alternatively, a light shielding member may be integrally formed in front of the lens array to prevent the crosstalk.
