Abstract:
A pulse-width data generating apparatus usable with a toner-transfer-type printing apparatus which responds to image data to form an output image, and arranged to generate pulse-width data causing a printing engine to form each pixel of a plurality of pixels forming the output image from gray-scale data of each pixel in the image data, said apparatus comprising:pulse-width generating means for receiving the image data to generate pulse-width data of each pixel corresponding to coordinates of each pixel in a NÃ—M pixel matrix on the output image and the gray-scale data of each pixel in the image data, wherein N and M are positive integers; and position-data generating means which receives and compares, to each other, the pulse-width data of adjacent pixels on both of two sides of each pixel on the output image to generate position data for controlling toner adhesion positions of each pixel.
