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.
Claims19
An exposure device comprising:
- an exposure section that includes a plurality of light emitting elements arranged along an axial direction of an image holding member that is rotatable, that is positioned with respect to the image holding member at both ends in the axial direction, and that exposes the image holding member to light by emitting light to the image holding member;
- a weight disposed so as to face the exposure section and having a mass determined in advance;
- and
- an elastic portion that is elastic and that is disposed between the exposure section and the weight to support the weight so as to be vibratable,
- wherein the elastic portion is disposed at each of one end and the other end of the weight in the axial direction, and attached to the exposure section via an attachment member.
An exposure device comprising:
- an exposure section that includes a plurality of light emitting elements arranged along an axial direction of an image holding member that is rotatable, that is positioned with respect to the image holding member at both ends in the axial direction, and that exposes the image holding member to light by emitting light to the image holding member;
- a weight disposed so as to face the exposure section and having a mass determined in advance;
- and
- an elastic portion that is elastic and that is disposed between the exposure section and the weight to support the weight so as to be vibratable,
- wherein the elastic portion includes a first elastic portion that is viscous and elastic and a second elastic portion that is elastic with a different temperature dependence from that of the first elastic portion.

- a weight disposed so as to face the exposure section and having a mass determined in advance;
- and
- an elastic portion that is elastic and that is disposed between the exposure section and the weight to support the weight so as to be vibratable,
- wherein the elastic portion includes a first elastic portion that is viscous and elastic and a second elastic portion that is elastic, the second elastic portion being less viscous than the first elastic portion.
