Abstract
A line head module faces a photoconductor drum, and is disposed such that light-emitting elements are arranged parallel to a rotational axis of the photoconductor drum to carry out exposure on the photoconductor drum, and the photoconductor drum is rotatably disposed. The line head module includes a line head having the plurality of light-emitting elements, and a condensing lens that condenses light in a direction crossing the arrangement direction of the light-emitting elements between the photoconductor drum and the side of the line head from which light is output.

A line head module which faces a photoconductor drum and is disposed such that light-emitting elements are arranged parallel to a rotational axis of the photoconductor drum to carry out exposure on the photoconductor drum, the photoconductor drum being rotatably disposed, comprising:
- a line head having the plurality of light-emitting elements;
- and
- a condensing lens that condenses light in a direction crossing the arrangement direction of the light-emitting elements between the photoconductor drum and the side of the line head from which light is output.
A line head module, comprising:
- a plurality of light-emitting elements arranged to face a photoconductor drum which is rotatably disposed,
- wherein the light-emitting elements are arranged such that an arrangement direction of the light-emitting elements is parallel to a rotational axis of the photoconductor drum, a condensing lens is disposed at a side of the line head from which light is output, and light output from the line head condensed by the condensing lens is exposed to the photoconductor drum.
