Abstract
An apparatus which forms an electrostatic latent image by exposing a charged photosensitive member with light. The apparatus identifies a pixel which has density value less than a threshold value and is sandwiched in a predetermined direction between two pixels having density values greater than or equal to the threshold value in image data, generates screen image data by screen processing on the image data, and outputs, for each of one pixel of the two pixels sandwiching the identified pixel and a pixel adjacent to the one pixel in the predetermined direction, an adjusted density value the screen image data.
