Abstract:
An image forming apparatus comprising:an exposure unit for exposing a photoreceptor charged to a predetermined potential to light;a controller for controlling exposure energy density of said exposure unit based on image information; anda development unit for visualizing an electrostatic latent image formed on said photoreceptor by said exposure unit, whereinsaid controller controls exposure energy density E.sub.dot (.mu.J/cm.sup.2) to be applied to an isolated one-dot pattern of said image information to satisfy a relation-0.11P+6.4.ltoreq.E.sub.dot /E.sub.line.ltoreq.-0.2P+10.7where E.sub.line (.mu.J/cm.sup.2) represents exposure energy density to be applied to a line pattern of said image information having lines on every second lines and P(.mu.m) represents dot pitch.
