OPTICAL PRINT HEAD AND IMAGE FORMING APPARATUS |
| 摘要 |
An optical print head, including: a light emitting substrate which includes a light emitting element on a base; a rod lens array which focuses light emitted from the light emitting element onto an image carrier, the rod lens array having a larger linear expansion coefficient than the base of the light emitting substrate; and expansion suppressing members which are attached to both lateral surfaces of the rod lens array in a direction that is perpendicular to an optical axis direction and is a shorter direction, each of the expansion suppressing members having a smaller linear expansion coefficient than the rod lens array. |
