Title:
【発明の名称】画像形成装置
Document Type and Number:
Japanese Patent JP3252973
Kind Code:
B2
Abstract:
Methods and apparatus are provided for forming images on a moving, charge retentive surface using a stream of radiant energy, modulated in imagewise fashion, wherein the intensity of the stream of radiant energy is controlled based on measured variations of the actual speed of the imaging surface from a set speed. In particular, a motion encoder, which is preferably the same motion encoder previously used to control the proper location of each line of information on the imaging surface is used to monitor the actual, instantaneous speed of the imaging surface to produce an actual speed signal. This actual speed signal is compared to a set speed signal to produce a speed variance signal which represents the difference between the actual imaging surface speed and the set speed. The variance speed signal is then used to control the intensity of the stream of radiant energy.
