    摘要： An imaging apparatus such that residual toner on a transfer/conveyer mechanism such as a transfer belt and an intermediate transfer material is effectively removable. High-tension voltage opposite in magnetic polarity (plus) to the charged toner and a photosensitive drum is applied to a discharger 15 provided ahead of a drive member 12 for driving a transfer belt 6. The residual toner on the transfer belt 6 is removed by a brush 21, and the residual foreign substances come in contact with the photosensitive drum 1 and move onto the photosensitive drum 1 before a printing operation is started. The foreign substances are then removed by a photosensitive drum cleaner.

    摘要： In an electrophotographic recording device, a multicolor toner image is formed by images in each color superimposed on one another. In order to detect image misalignment, image-forming units form a color registration detection pattern, and sensors detect the pattern and output detection signals. A control unit detects the position of the patterns based on only portions of the detection signals corresponding to leading edges of the patterns.
