摘要： An image forming apparatus includes: a first optical head group including first optical heads arranged in a sub-scanning direction; a second optical head group including second optical heads arranged in the sub-scanning direction and overlapping the first optical head group in a main scanning direction; a detector that detects displacement amounts between the first optical heads and the second optical heads; and a controller that performs registration based on the detection by the detector. The controller performs, with one of the first optical heads as a reference, registration on the other first optical heads, performs, with one of the second optical heads as a reference, registration on the other second optical heads, and performs registration between the first optical head group and the second optical head group based on a displacement amount between one of the first optical heads and one of the second optical heads.

摘要： A lens array includes a plurality of lens assembly members with a plurality of lenses and a light blocking member with a plurality of apertures arranged therein. The lens assembly members are arranged so that an optical axis of each of the lenses of one of the lens assembly members is aligned with an optical axis of each of the lenses of another of the lens assembly members.
Further, the lens assembly members and the light blocking member are arranged so that the following relationship is satisfied:

where PY is a pitch of the lenses in one row, PX is a pitch of the rows, F is a focal length of each of the lenses, LO is a distance between each of the lenses and an object surface thereof, and RA is a distance between the optical axis and an inner surface of the aperture.

摘要： An image-forming device includes a first frame (15), and a first supporting unit (161). The first frame includes a first plate-shaped (15A) part having a surface orthogonal to the first direction and supports a first image-bearing member (53). The first plate-shaped part is formed with at least two first positioning holes (166C,166D). The first supporting unit erects from the first plate-shaped part and includes at least two first fitting parts (161C,161D) and a first contact part (161A). The at least two first fitting parts fit into the at least two first positioning holes. The first contact part extends in the first direction from each of the at least two first fitting parts. The first contact part contacts and supports an exposure unit (40). The exposure unit is oriented in a direction in which the light emitted from the plurality of light emitting elements is directed toward a second direction orthogonal to the first direction.
