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.
