    摘要: The scanning lens unit includes lenses located between a optical deflector and a lens having a k-th lens surface Sk from a first lens surface S1 closest to the deflector are disposed such that a height of a lens having the lens surface Sk denoted by πk satisfies the predetermined expression. each of lenses located between the first lens surface S1 and the k-th lens surface Sk is a cylindrical lens having power only in the determined deflection direction. Therefore, the lenses can individually have minimum thicknesses, as a result, the cost reduction of the scanning lens unit is realized. The optical scanning apparatus includes the scanning lens and hence can achieve cost reduction.

    摘要: A first fθ lens is arranged to form an inclination angle α1 to a main scanning plane. A second fθ lens is arranged to form an inclination angle α2. In order to determine the inclination angles α1 and α2, curvature amounts of scanning lines generated on a scanned surface are measured when the fθ lenses are independently inclined one at a time at a minute angle. Change rates K1 and K2 are obtained from the measured curvature amounts and the minute angles. The inclination angles α1 and α2 are determined such that |K1 α1+K2 α2| is no more than a certain value.

    摘要: In a color image recording system, a color image is recorded on a photosensitive material by causing red, green and blue light beams modulated according to a color image signal to scan the photosensitive material one after another in the order of the red, green and blue light beams, respectively. A photodetector detects only the red light beam, and the red, green and blue light beams are caused to start recording the colorings at respective predetermined times T1, T2 and T3 (T1
