ABSTRACT:
A recording apparatus for use with a radiation-sensitive member includes a holder for holding the radiation-sensitive member, an image forming system for applying a radiation energy, having a pattern of distribution, to the radiation-sensitive member to form an image thereon, a vibration meter for measuring vibration to detect relative movement between the radiation-sensitive member and the pattern of the radiation energy to be applied to the radiation-sensitive member, and a discriminating circuit for discriminating, on the basis of the output from the vibration meter, whether the image forming system is to be actuated, whereby any positional deviation of or any distortion in the image is mitigated.
