摘要： An image forming apparatus includes: an image carrier; a development unit for forming a toner image on the image carrier by supplying a toner contained in a developer reservoir to a latent image formed on the image carrier by means of a developer carrier; a transfer unit for transferring the toner image formed on the image carrier onto a transfer medium; a recovery unit for recovering the toner remaining on the image carrier after image transfer; a return unit for transporting the recover toner recovered by the recovery unit so as to return the recover toner into the developer reservoir of the development unit; and a separator/feeder for separating the toner contained in the developer reservoir from the recover toner thereby exclusively feeding the toner contained in the developer reservoir to the latent image formed on the image carrier by means of the developer carrier.

摘要： A tractor feeds a perforated continuous paper sheet to a printing position. The feeding force of a fusing device located downstream of the printing position is set larger than the feeding force of the tractor in order to apply tension to the continuous paper sheet at the printing position. A braking device located upstream of the tractor applies a braking force balancing with the feeding force of the fusing device to the continuous paper sheet. The braking force of the braking device is varied depending upon the properties of the paper sheet or the environmental conditions. This arrangement makes it possible to stabilize the feeding state even under situations where the sheet feeding force is likely to become unstable, thereby realizing printing without any deviation from the predetermined position. Further, this arrangement can also prevent hole breakage to occur.

摘要翻译： 拖拉机将穿孔的连续纸张送到打印位置。 位于打印位置下游的定影装置的进给力设定为大于拖拉机的进给力，以便在打印位置向连续纸张施加张力。 位于拖拉机上游的制动装置利用定影装置的进给力对连续纸张施加制动力平衡。 制动装置的制动力根据纸张的性质或环境条件而变化。 这种布置使得即使在片材进给力可能变得不稳定的情况下也可以稳定进给状态，从而实现打印，而不会偏离预定位置。 此外，这种布置也可以防止发生孔破裂。

摘要： A method and apparatus for rolling a recording paper is disclosed which is characterized by causing first nipping means disposed on a cylindrical drum to nip one end of the recording paper, rotating the cylindrical drum thereby rolling the recording paper around the cylindrical drum, causing second nipping means to nip the other end of the recording paper, and moving the first nipping means so as to bring the recording paper into close contact with the cylindrical drum. Owing to the construction, the recording paper and the ink sheet can be easily and infallibly brought into close contact with the cylindrical drum.
