摘要： A transfer device includes a photosensitive drum on the outer surface of which an image to be transferred is formed; a transfer drum arranged in parallel to the photosensitive drum and substantially in contact with the outer surface of the photosensitive drum, the transfer drum capable of adsorbing a sheet on its outer surface; and a sheet guide for guiding the sheet supplied toward the transfer drum to a transfer position between the photosensitive drum and the transfer drum. At an end of the sheet guide on the side of the transfer position, a hill-shaped guide is provided which flexes at a flexing point in a plane orthogonal to the rotary axis of each of both drums so as to be convex toward the photosensitive drum. The side of the hill-shaped guide from the flexing point toward, and closest to, the transfer position is inclined toward the photosensitive drum with respect to a tangent of the photosensitive drum passing the transfer position.

摘要： An image forming apparatus which prevents the toner image, which is transferred onto the recording sheet but not yet fixed thereto, from being scattered, by reducing the amount of the charge, which is generated by the pre-cleaning charge removal means and attaches to a recording sheet on a transfer-member supporting member after it passes the image transfer stage. In the image forming apparatus, a recording sheet is transported in a state that it is electrostatically attracted onto a drum sheet, a toner image is formed on a photoreceptor drum in accordance with image information, and the toner image is transferred from the photoreceptor drum onto the recording sheet by using a transfer corotron disposed on the rear side of the drum sheet. Further, in the image forming apparatus, a conductive plate is provided which substantially prevents the negative charge of the same polarity as of the toner, generated by the pre-cleaning charge removal means, from attaching to the recording sheet after it passes an image transfer stage.

摘要： An image forming apparatus includes an image carrying body on which a toner image is created. A sheet carrying/transporting rotational body adsorbs a recording sheet to which the toner image on the image carrying body is transferred, and transports the sheet. The recording sheet is detached after transfer from the sheet carrying/transporting rotating body, and an assisting device thrusts against the non-image area of the recording sheet to limit its detachment from the sheet carrying/transporting rotating body. The image forming device can prevent transportation failure and image smudging that is otherwise generated when a thick sheet provided with a curl before it is adsorbed to a sheet carrying/transporting rotational body is detached in the curved state from the rotational body and transported to a fusing means.
