Exposure device, image forming apparatus, and computer-readable medium

An image forming apparatus comprising:

• a photosensitive body;
• an exposure device including a plurality of light-emitting elements for exposing the photosensitive body to form an electrostatic latent image;
• and
• a developing device that develops the electrostatic latent image with a toner, wherein
• the exposure device includes:
• an exposure section that has the plurality of light-emitting elements,
• a light amount detection unit that detects light amounts of the light-emitting elements,
• a controller that sequentially determines control values of the respective light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value, wherein the control values of the respective light-emitting elements are used to cause the respective light-emitting elements to emit light and carry out exposure,
• a plurality of holding units that are provided for the light-emitting elements, respectively, wherein each holding unit holds a control voltage of the controller, and
• a connection unit,
• when the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plurality of light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.

A computer-readable medium storing a program causing a computer to execute an exposure control process, the exposure control process comprising:

• controlling an exposure device including
• a plurality of light-emitting elements,
• a light amount detection unit that detects light amounts of the light-emitting elements,
• a controller that sequentially determines control values of the respective light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value, wherein the control values of the respective light-emitting elements are used to cause the respective light-emitting elements to emit light and carry out exposure, and
• a plurality of holding units that are provided for the light-emitting elements, respectively, wherein each holding unit holds a control voltage of the controller,
• when the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, to connect the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plurality of light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.
