Imaging apparatus and imaging method to increase efficiency of mounting/demounting of a recording material to/from a recording drum

摘要

A plate is consecutively mounted on the outer peripheral surface of a recording drum under pressure from a squeegee roller, with its leading edge clamped by leading edge clamps. Guide members for causing the squeegee roller to climb up thereon are provided on the outer peripheral surface of the recording drum such that the squeegee roller is prevented from interfering with the leading edge clamps during plate mounting. Without the need to stop the rotation of the recording drum during plate mounting, a time period required for plate mounting can be reduced.
