Abstract: A development device includes an imaging lens and light shielding walls. The imaging lens includes a body part having a constant diameter and both end parts arranged at both ends in an optical axial direction having diameters larger than the body part to capture a reflected light from a document onto an imaging part. The light shielding walls has a space with an interval larger than the diameter of the body part and smaller than the diameters of the both end parts, allowing the body part of the imaging lens to be arranged in the space, and shielding a light in the optical axial direction.

Abstract: A protruding locking pawl is provided at an end of a light guide which corresponds to a first light input surface. A recessed locking portion is formed in a frame so that the locking pawl can be locked in the locking portion. A light blocking member is slidably loosely inserted into a position where the light blocking member covers a longitudinal end of the light guide which corresponds to a second light input surface. Even if expansion and contraction occurs in the longitudinal direction of the light guide, the design dimensions of a first gap A and a second gap B can be maintained; the first gap A is formed between the first light input surface and a first light source, and the second gap B formed between the second light input surface and a second light source. Therefore, possible leakage current can be prevented.
