Embodiment approach

[0074] Figure 22 and Figure 23 represents another embodiment. Figure 22 It is a transverse cross-sectional view of the holding member 62 in a state in which the boss portion 62 a is in contact with the rear bearing plate 47 as viewed from the lower side. Figure 23 It is a transverse cross-sectional view of the holding member 62 in a state in which the boss portion 62 a is in contact with the front bearing plate 47 as viewed from the lower side.

[0075] In this embodiment, on the inner surface (side surface of the groove 49d) of the second rail portion 49c on the side of the left arm portion 62b, there are protrusions protruding from the front side moving end and the rear side moving end of the holding member 62, that is, near the bearing plate 47. Connecting portion 49e.

[0076] Accordingly, when the holding member 62 moves from the end portion of the second rail portion 49c toward the opposite end portion, the posture correcting member 48 can be reliably moved behind...

Abstract

The invention provides an optical scanning device and an image forming apparatus. The optical scanning device includes a holding member. The holding member has a boss part and a right arm part that extends from the boss part in a direction perpendicular to the movement direction of the holding member and holds a cleaning member. The boss part is mounted with a posture correction member relativelymovable in the movement direction of the holding member. The posture correction member is movably inserted into a groove between two second rail parts, and when the holding member moves, the posture correction member moves later than movement of the holding member, so that an inclined posture of the holding member is corrected by the delay operation in a direction perpendicular to the second railpart. According to the invention, the cleaning member can move stably, and the cleaning performance of the cleaning member can be improved.

Description

technical field [0001] The present invention relates to an optical scanning device and an image forming device including the optical scanning device. Background technique [0002] Conventionally, an image forming apparatus adopting an electrophotographic method such as a copier or a printer has an optical scanning device for emitting light for forming an electrostatic latent image on a photosensitive drum, and a developing device for forming an electrostatic latent image on a photosensitive drum. The electrostatic latent image on the photosensitive drum is developed as a toner image. [0003] The optical scanning device has a housing that accommodates a polygon mirror, an imaging lens, and the like. A light exit for light exit is formed on the casing. The light exit is constituted by an opening extending in a predetermined direction. The light exit is closed by a transparent cover. [0004] Therefore, if stains such as toner or dust adhere to the surface of the transpare...
