ABSTRACT:
An electrophotographic recording apparatus including a light-sensitive drum for carrying toner images developed thereon, and a transfer unit arranged at a prescribed distance from the light-sensitive drum for transferring the toner images from a light-sensitive drum to the image recording paper. The transfer unit has a charging wire electrode for electrically charging the paper and a generally inverted U-shaped housing having spaced sidewalls with respective bottom edges. A separator is provided for separating the paper from the light-sensitive drum as the paper travels along a conveying path and comprises a paper separating plate extending from the downstream one of the bottom edges of the housing of the transfer unit in the downstream direction of the travel of the paper along the conveying path side thereof, with and the housing of the transfer unit is grounded. The paper separating plate has a distal end having a saw tooth shape along the length thereof, as measured transversely to the conveying path.
