Abstract
A light emitting device includes a light-emitting element row that includes light emitting elements arranged in a row in a main scanning direction, an optical element that is used for forming an electrostatic latent image by focusing light outputs of the light emitting elements and exposing a photoconductor to light and a control unit that controls light emission of the light-emitting element row. The light-emitting element row is divided into groups, and the control unit uniformly corrects a light intensity of each of the light emitting elements included in the groups on a group-by-group basis by a first correction method so as to correct density unevenness in the main scanning direction.

A light emitting device comprising:
- a light-emitting element row that includes light emitting elements arranged in a row in a main scanning direction;
- an optical element that is used for forming an electrostatic latent image by focusing light outputs of the light emitting elements and exposing a photoconductor to light;
- and
- a control unit that controls light emission of the light-emitting element row,
- wherein the light-emitting element row is divided into a plurality of groups, and
- wherein the control unit uniformly corrects a light intensity of each of the light emitting elements included in the groups on a group-by-group basis by a first correction method so as to correct density unevenness in the main scanning direction.
An image forming apparatus comprising:
- a toner-image forming unit that forms a toner image by using a light-emitting element row that includes light emitting elements arranged in a row in a main scanning direction and an optical element that is used for forming an electrostatic latent image by focusing light outputs of the light emitting elements and exposing a photoconductor to light;
- a transfer unit that transfers the toner image onto a recording medium;
- a fixing unit that fixes the toner image transferred to the recording medium onto the recording medium in such a manner as to form an image;
