    摘要： A color image forming apparatus in which an engine controller outputs an operation start signal to write controllers at a timing at which a registration sensor detects a position of a sheet of transfer paper. Synchronization detection signals for colors are used to set reference positions for front edges of the colors in a main scanning direction. A write controller for a reference color outputs a write-operation start signal so as not to cut the synchronization detection signals each indicating one line for one color in the main scanning direction and line synchronization signals, into two parts in their longitudinal direction. The write-operation start signal is used to set a reference time point when the write controllers make transfer requests for image signals for the colors to an image processor.

    摘要： A forming unit forms a latent image of input image data. A counter counts number of times of forming the latent image in a sub-scanning direction, in which an upper limit of the number of times is set. A first control unit controls the forming unit to form the latent image based on the upper limit. A determining unit determines whether a latent image forming is performed by the forming unit exceeding the upper limit. When the determining unit determines that the latent image forming is performed exceeding the upper limit, a second control unit controls, the forming unit to continue to form the latent image.
