Patent ID: 7315712

Claim:
An electrophotographic image recording apparatus for forming an image, the apparatus comprising: a photoconductive image bearing member; charging means which uniformly charges said photoconductive image bearing member; exposure means that exposes a surface of said photoconductive image bearing member after said charging means charges said photoconductive image bearing member, to form an electrostatic latent image on the surface of said photoconductive image bearing member; development means which adheres a toner onto said electrostatic latent image to form a toner image with a hyperchromic toner or a hypochromic toner, the hyperchromic toner and hypochromic toner having substantially the same hue; and transfer means which transfers the toner image formed by development means onto a transfer material; wherein said exposure means forms the electrostatic latent image on the surface of said image bearing member in a writing resolution for an image formed with the hypochromic toner which is higher than a writing resolution for an image formed with the hyperchromic toner.
