    摘要： An image forming apparatus for forming an image on an image forming body by scanning a plurality of modulated laser beams is disclosed. The apparatus is provided with a generator to generate a plurality of reference signals each with a differrent phase from other reference signals, a detector for detecting the difference of image density between two adjacent image pixels, combined modulator to generate a modulated laser beam by combining a selected laser beam, a selected reference signal and the image density. The detector classifies each pixel as one of an edge starting pixel, an edge ending pixel, and a non-edge pixel based on the value of image density difference relative to positive and negative threshold values. The selection of the laser beam and the reference signal is based on the image density difference detected by the detector and the class of the pixel.

    摘要： An apparatus for forming images on at least one surface of a sheet includes a reader for reading image information on documents, a memory for storing image signals output by the reader, and an image forming unit for selectively forming one of: (i) two page toner images corresponding to the image signals of two pages of the documents separately on two image carrying members, and (ii) a single toner image on one of the two image carrying members. A jam detector detects a jammed sheet, and a delivery detector detects delivery of a copied sheet to outside the apparatus. Image signals are eliminated from memory in accordance with a progression of image formation. If the jam detector detects the occurrence of the jammed sheet, a control unit prohibits the memory from eliminating the image signals until the delivery detector detects a next sheet delivered from the apparatus, so that the selected image expected to be formed by the image forming unit on the jammed sheet may be properly formed on a following sheet based on the image signals retained in the memory. A selector is provided for selecting one of a both-surface copy mode and a single-surface copy mode, wherein the control unit controls the memory to store the image signals corresponding to two pages of the documents when the both-surface copy mode is selected and to store the image signals corresponding to the single page of the documents when the single-surface copy mode is selected.
