Abstract
Disclosed is an exposure head including a light emitting element array including light emitting elements disposed in a first direction, a light blocking member including an aperture stop through which lights emitted from the light emitting elements pass, and an image forming optical system that makes an image by using the lights having passed through the light blocking member. An absolute value of a magnification in the first direction of the image forming optical system is equal to or more than 0.7 times and is equal to or less than 0.8 times.
Claims8
An exposure head comprising:
- a light emitting element array including light emitting elements disposed in a first direction;
- a light blocking member including an aperture stop through which lights emitted from the light emitting elements pass;
- and
- an image forming optical system that makes an image by using the lights having passed through the light blocking member,
- wherein an absolute value of a magnification in the first direction of the image forming optical system is equal to or more than 0.7 times and is equal to or less than 0.8 times.
An image forming apparatus comprising:
- a latent image carrier on which a latent image is formed;
- an exposure head;
- and
- a development unit that develops the latent image formed on the latent image carrier by the exposure head,
- wherein the exposure head includes:
- a light emitting element array including light emitting elements disposed in a first direction;
- a light blocking member including an aperture stop through which lights emitted from the light emitting elements pass;
- and
- an image forming optical system that allows the lights having passed through the light blocking member to transmit therethrough so that the latent image carrier is exposed,
- wherein an absolute value of a magnification in the first direction of the image forming optical system is equal to or more than 0.7 times and is equal to or less than 0.8 times.
