  • Patent number: 5268724
    Abstract: A transfer apparatus including a photoreceptor drum having a transfer position, feeding rollers for feeding out a sheet of paper upward obliquely, and a guide member provided between the feeding rollers and the photoreceptor drum and having a guide surface on a lower surface thereof to guide the paper to the transfer position along the guide surface. In the transfer apparatus, the structure is simplified since the paper is guided by the single guide member. Moreover, the feeding of the paper can be performed smoothly, since frictional resistance is produced only on one side of the paper. In addition, the guide surface is formed on the lower surface of the guide member, so that the paper can be supplied to the transfer position of the photoreceptor drum stably.
