    摘要： Electrophotographic printing apparatus where the toner image is transferred to the underside of a paper sheet and where the paper sheet is guided from a transfer station (B) to a fixing unit entrance (A), by a grid plate to which the paper sheet adheres owing to suction means (10), the grid plate forming a guiding surface extending from the transfer station towards the fixing unit entrance, and diverging from the plane defined by the transfer station and the fixing unit entrance of an angle such that the path followed by the paper from the transfer station to the entrance of the fixing unit is slighty greater than their distance, whereby allowance is provided for paper contractions and undersired paper tensioning is prevented.

    摘要： An electrostatic copying apparatus comprising a fixing device with an electrical heating element (406), a temperature detecting means (430) for detecting temperature at a predetermined position of the fixing device, a copying cycle signal producing means (438) for producing a copying cycle signal according to the performance of the copying cycle, a power supply switch (440), and control means for the electrical heating element and the power supply switch is provided. The control means (250) upon the closing of the power supply switch (440) energizes the electrical heating element (406) until the temperature detected by the temperature detecting means (430) reaches a first predetermined temperature T₁. Thereafter, when the copying cycle signal is produced, said control means (250) controls the energization and deenergization of the temperature detected by the temperature detecting means (430) is the first predetermined temperature T₁, and wherein when the copying cycle signal is not produced, said control means (250) deenergizes the electrical heating element (406), and turns off the power supply switch (440) when the temperature detected by the temperature detecting means (430) is lowered to a second predetermined temperature which is lower than the first predetermined temperature.

    摘要： The present invention relates to an image forming apparatus comprising a main image forming mechanism (20) for forming a toner image on a recording sheet (40) based on image information and an auxiliary image forming mechanism (30) for forming an auxiliary image on a recording sheet (40) on which the main image is formed. The auxiliary image forming mechanism (30) supplies charged toner to a substrate provided with a plurality of toner passages holes and selectively forms electric potential which allow or does not allow the charged toner to pass through each toner passage hole by a pair of electrodes. A predetermined image is formed with the toner passed through the toner passage holes.

    摘要： An electrophotographic printer is provided with: a photosensitive drum(10); a feeding device(22) which feeds a continuous recording sheet(S); a transfer device(20) which transfers a toner image formed on the photosensitive surface(12) of the drum(10) onto the sheet(S); a cleaning device(116) which removes residual developer from the photosensitive surface(12); and a photographic fixing device(140) which fixes the toner image to the sheet-(S). The feeding device(22) includes an endless belt-(64) which is located on the downstream side of the drum(10) with reference to the sheet-feeding direction and which travels in one direction. The feeding device(22) also includes a charger(88) which electrically charges the endless belt(64), so as to allow the sheet to be electrostatically attracted on the endless belt(64).
