Abstract
The inner drum exposure apparatus records an image by scanning a recording material held on an arcuate inner peripheral surface of a support with a light beam that is emitted from a light source and modulated in accordance with image information and deflected by a total reflection mirror plane of a rotatably driven scanning device such as a spinner. The scanning device includes a first cylindrical lens for condensing the incident light beam incident into the total reflection mirror plane along a first plane containing an optical axis of the light beam and a second cylindrical lens for scattering the light beam along a second plane orthogonal to the first plane. The incident light beam is shaped into a beam spot of an elliptical configuration whose major axis is orthogonal to a beam deflecting/scanning direction by the first and second cylindrical lenses.
