摘要： A developing device for an image forming apparatus of the present invention includes an image carrier performing endless movement while carrying a developer in the form of a layer thereon, and a regulating member for regulating the thickness of the layer Toner stored in the developing device is covered with an additive whose particle size is less than 2 &mgr;m. The regulating member is implemented as a doctor roller having a surface roughness Rz equal to or greater than the above particle size, but smaller than 2 &mgr;m. The doctor roller is pressed against a developing roller or developer carrier by a preselected pressure, forming a nip for development The developing device reduces irregular development ascribable to impurities caught at a regulating position assigned to the doctor roller more than a conventional developing device using a doctor blade as a regulating member. In addition, the developing device obviates irregular development in the form of fine stripes ascribable to stripe-like irregularities formed in the developer layer existing on the developing roller.

摘要： In an image forming reflecting mirror for a constant speed optical scan, a light beam is convergent in a cross scan-corresponding direction with a point near a starting point of deflection as a starting point of the light beam, and the light beam is deflected at an equal angular velocity and is converged to form a light spot on a scanned face so as to optically scan the scanned face at a constant speed. The image forming reflecting mirror has a shape on a deflecting-reflecting face represented by the following general formula, Y.sup.2 =2RmX-(K+1)X.sup.2, where X designates a coordinate in the direction of an optical axis and Y designates a coordinate in a direction perpendicular to the optical axis with a position on the optical axis as an origin, and Rm designates a radius of curvature on the optical axis and K designates a conical constant. The image forming reflecting mirror has a concave mirror face of a barrel or saddle type in the cross scan-corresponding direction which is separated by a distance Rs from a mirror face on the optical axis and is formed by rotating the shape with an axis perpendicular to the optical axis on the deflecting-reflecting face as a rotational axis. A new conical constant E=K+1 satisfies the following condition, -2.ltoreq.E.ltoreq.15.

摘要： In an optical scanner, a deflected light beam is reflected on a reflective image forming element and is converged as a light spot on a scanned face through an elongated lens to perform an optical scanning operation at an equal speed. The reflective image forming element has a reflecting face with rotation symmetry and converges a reflected light beam onto the scanned face in a main scan-corresponding direction. The elongated lens has a barrel type toroidal face as an incident face and has a normal toroidal face as a light emitting face. The elongated lens sets the scanned face and the forming position of a linear image to a substantially conjugate relation in a cross scan-corresponding direction in cooperation with the reflective image forming element. A conjugate magnification m.sub.0 in the conjugate relation of the reflective image forming element and the elongated lens with respect to an image height 0 of the light spot satisfies the following condition: 1>m.sub.0 >0.35.
