子写真記録装置。 A photosensitive drum rotating at a constant speed that forms a copy image based on the exposed image formed by the optical head and transfers the copy image onto a recording paper, a paper feeding means that feeds the recording paper to a transfer portion of the photosensitive drum, and a recording paper. and recording paper detection means for detecting movement of the recording paper,
The sum of the length from the recording paper detection means to the transfer section of the photosensitive drum and the margin length at the leading end of the recording paper is:
The recording paper detecting means is disposed so as to be longer than the length from the exposure part to the transfer part on the photosensitive drum,
An electrophotographic recording apparatus further comprising a control means for controlling the drive timing of the optical head based on a detection output of the leading edge of the recording paper by the recording paper detection means.
