Abstract:
An electrophotographic apparatus comprising:an electrostatic recording unit which forms a dot latent image in conformity with binarized image dot data through lighting of a scanning light on a latent image carrier in motion and which, after development with a toner component, transfers dots onto record paper; anda quantity-of-light control unit which, for each lighting noticeable dot among said image dot data, provides a control of an amount of optical energy for use in formation of a latent image of said noticeable dot such that said noticeable dot can have a certain dot diameter on said record paper, on the basis of peripheral dots which may have influence on a size of said noticeable dot on said record paper,wherein said quantity-of-light control unit defines, as a reference value of optical energy of said noticeable dot, optical energy required for formation of a solid part of an image on said record paper on which all dots are transferred, and wherein said quantity-of-light control unit, when peripheral dots are turned off, controls the optical energy to be equal to a value obtained by adding to said reference value a quantity-of-light optical energy which has been compensated for by light-emission of said peripheral dots, andwherein said quantity-of-light control unit provides a control of optical energy of said noticeable dot in response to a distance from said peripheral dots.
