摘要： A technique suppresses the influence of the components that can give rise to fluctuations in the magnetic field and arranged near the motor for driving the polygon mirror on the operation of driving the motor without obstructing the trend of downsizing image forming apparatus. An image forming apparatus comprises a motor that drives a polygon mirror for forming a scanning pattern on the photosensitive surface of a photosensitive material by scanning light, a development section that forms a toner image on the photosensitive surface by means of magnets that can reciprocate relative to the photosensitive surface and a magnetic body that is arranged in a predetermined region between the motor and the development section and shields the magnetic force of the magnets of the development section to prevent it from influencing the motor.

摘要： The multi-beam optical unit of the invention limits the number of reflection times by half mirrors to one time or below when a plurality of beams are combined into one and guided to a polygon mirror, so that an influence upon an image due to a positioning error of the half mirrors can be minimized. Besides, power of emitted beams can be made uniform by using the half mirrors having transmissivity and reflectance satisfying predetermined conditions regardless of the number of times that the beams penetrate the half mirrors. Thus, the service lives of a plurality of beam emitting sources can be made uniform, and maintainability can be improved.
