Image forming apparatus

A print head for an image forming apparatus, comprising:

• a light emitting element array that includes a plurality of light emitting elements configured to emit light that forms a latent image on a photosensitive member;
• a transparent member that is positioned between the photosensitive member and the light emitting element array, has a relative position fixed with respect to the light emitting element array, and transmits the light emitted from the light emitting element array;
• a holder fixedly coupled to the transparent member;
• a gap spacer configured to engage both the holder and the photosensitive member to maintain a constant distance between the photosensitive member and the transparent members and
• a biasing member configured to apply a biasing force to bias the holder toward the photosensitive member,
• wherein the transparent member extends between the biasing member and the gap spacer such that the biasing member applies the biasing force through the transparent member.

An image forming apparatus, comprising:

• a light emitting element array that includes a plurality of light emitting elements fixedly coupled to a transparent substrate;
• a photosensitive member that forms a latent image by being exposed to light emitted from the light emitting element array;
• a lens that is disposed between the light emitting element array and the photosensitive member, and that is configured to condense the light emitted from the light emitting element array on the photosensitive member;
• a holder fixedly coupled to the lens and the light emitting element;
• a gap spacer configured to maintain a constant distance between the photosensitive member and the light emitting element array;
• and
• a biasing member configured to bias the transparent substrate toward the photosensitive member,
• wherein the biasing member, the gap spacer, and the transparent substrate are aligned.
