摘要： To make it possible to improve a printing speed. When printing a plurality of printing sheets 14, it is possible to decrease the time for generating correction data by using a pair of correction data values to print the printing sheets 14. Therefore, it is possible to decrease the time for printing each printing sheet 14 even compared to the case of a method for generating correction data for each printing sheet 14. As a result, even when the number of sheets to be printed is large, it is possible to improve a printing speed. Moreover, when meandering states of the printing sheet 14 are changed, it is possible to prevent disorder of a printed image due to meandering of the printing sheet 14 for a long time by newly generating correction data. Furthermore, by generating (updating) only a part of correction data when newly generating the correction data, it is possible to decrease the time for generating the correction data and improve a printing speed.

摘要： An image formation apparatus of the present invention forms an electrostatic latent image on a moving photosensitive belt by a laser beam produced by a laser device. A belt edge detector 1 detects an edge portion (belt edge) of a photosensitive belt 100 in a main scanning direction. A virtual edge detection circuit 2 generates a virtual edge detection signal 2A which changes a generation timing in accordance with a change of a detection timing of the belt edge detected by the belt edge detector 1. The generation timing of the virtual edge detection signal 2A does not almost follow the detection timing of the belt edge which changes by flaws and non-linearity of the belt edge, and changes in accordance with a slow change of the detection timing. A synchronizing signal generation circuit 3 and a driving circuit 4 drives the laser device so as to start a writing of an image data by the laser beam in synchronization with the virtual edge detection signal.
