摘要： A lens unit includes first and second arrays of microlenses. The microlenses in the first array have mutually parallel optical axes and are aligned in a meridional direction orthogonal to their optical axes. The microlenses in the second array are aligned in the same direction as the lenses in the first array, and have optical axes that coincide with the optical axes of corresponding microlenses in the first array. The microlenses in the first array collimate light incident in a sagittal plane orthogonal to the meridional direction. The microlenses in the second array focus the collimated light in the sagittal plane. The lens unit is useful in the scanning heads of scanning devices, the LED heads of LED printers, and in the exposure devices of other electrophotographic image forming apparatus.

摘要： An image forming apparatus includes a rotating photoconductive drum, charging roller, exposing unit, developing unit, transfer roller, cleaning blade, and controller. The charging member charges the surface of the photoconductive drum. The exposing unit illuminates the surface charged by the charging roller to form an electrostatic latent image. The developing unit develops the electrostatic latent image into a toner image. The transfer roller transfers the toner image onto a recording medium. The cleaning blade removes residual toner that failed to be transferred onto the recording medium. Prior to the discharge of deteriorated toner in the developing unit, the charging member charges the photoconductive drum which in turn charges the transfer roller. The toner discharged from the developing unit remains on the photoconductive drum when an area on the photoconductive drum passes by the transfer roller as the photoconductive drum rotates.
