Abstract: An image recording apparatus includes an image carrying part, a developing part and an image transferring part. The image carrying part has a surface on which an electrostatic latent image is formed. The developing part develops the electrostatic image into a toner image by selectively applying toner to the surface of the image carrying part. The image transferring part transfers the toner image onto a recording sheet or an intermediate image transferring part. Fine particles are uniformly formed on the surface of the image carrying part, and a portion of the fine particles is transferred from the image carrying part with the toner image. The fine particles are smaller in diameter than the toner particles.

Abstract: Method and apparatus for non-destructive inspection of flaws in metal materials include exciting coils centered on a longitudinal axis of a cylindrical or columnar metallic material to be examined being arranged to surround the examinee material. A multiphase alternating current of such a relatively low frequency as to cause the exciting coils to generate a rotating magnetic field which rotates about the longitudinal axis of the examinee material is superimposed with a high frequency alternating current having an inspection frequency selected on the basis of the necessary sensitivity for detection of surface flaws of the examinee material. The composite multiphase current is applied to the exciting coils so that an electromagnetic effect induced in the surface of the examinee material by the high frequency alternating current is rotated for shifting circumferentially about the examinee material along with the rotating magnetic field.
