Abstract
In a line head, a plurality of element arrays arranged in a first direction. Each array includes a plurality of light emission elements arrayed in a second direction which is perpendicularly to the first direction, The light emission elements emit light for forming an electrostatic latent image on a photosensitive surface of an image carrier. A switcher activates the light emission elements in at least one of the element arrays while deactivating the others. A developer develops the latent image as a visible image with toner.

A line head, comprising:
- a plurality of element arrays arranged in a secondary scanning direction, each array including a plurality of light emission elements arrayed in a primary scanning direction;
- and
- a first switcher, which activates the element array in at least one of the element arrays while deactivating the others,
- wherein the first switcher sequentially activate at least one of the element arrays in accordance with an image to be formed.
An image forming apparatus, comprising:
- an image carrier, having a photosensitive surface;
- a line head, comprising:
- a plurality of element arrays arranged in a secondary scanning direction, each array including a plurality of light emission elements arrayed in a primary scanning direction;
- and
- a first switcher, which activates the element array in at least one of the element arrays while deactivating the others;
- and
