ABSTRACT:
An optical scanner comprising an image forming mirror for an equal speed optical scan and for field curvature correction, a light beam is emitted from a light source device and is deflected by an optical deflector at an equal angular velocity. This deflected light beam is converged onto a scanned face and a scanning speed of a light spot on the scanned face is equalized. The image forming mirror has a reflecting face formed in coaxial, aspherical and concave shapes. The reflecting face is obtained by rotating a curve X(H) represented by the following formula, }!+.SIGMA.Ai.multidot.H**i
around an X-axis. The curve X(H) is set such that a parameter .DELTA.X(H) represented by
satisfies the following condition (I),
