摘要： In the tri-level process in which positive and negative latent images are formed on a photosensitive body and then developed using toners of two colors (for example, red and black) charged respectively to opposite polarities with respect to the polarities of the latent images, there has been a problem of degrading the quality of a two-color picture by the appearance of a special phenomenon in which red toner is attached around a black image and black toner is attached around a red image by attraction of the reverse electric field. An exposure control is performed in order to suppress the fringe phenomenon.

摘要： A double beam scan type optical apparatus for use in a laser printer or the like. Such apparatus comprises two light sources and a lens system which provide scanning means for scanning a surface with parallel output light beams of the two light sources and beam distance controlling means for controlling the distance between the light beams. The reliability of the invention is improved by monitoring the intensity of the beams. Beam intensity checking means provide signals to verify that the intensity of each beam is maintained equal thus assuring that no abnormal conditions exist with the light sources or the lens system of the apparatus.
