The present invention solves the problem arising when a photosensitive medium and some or all of means for forming a latent image on the photosensitive medium are made into a unit which is removably mountable with respect to the body of an apparatus. This problem is attributable to the fact that the characteristic of the photosensitive medium is not constant, and lies in that the completed electrostatic latent image differs from one photosensitive medium to another. The present invention solves this problem by providing an adjusting function to the means of such unit itself used to form a latent image.
