Abstract
An exposure device includes an exposure section, a weight, and an elastic portion. The exposure section includes plural light emitting elements arranged along an axial direction of an image holding member that is rotatable, is positioned with respect to the image holding member at both ends in the axial direction, and exposes the image holding member to light by emitting light to the image holding member. The weight is disposed so as to face the exposure section, and has a mass determined in advance. The elastic portion is elastic, and is disposed between the exposure section and the weight to support the weight so as to be vibratable.
