摘要： A paper feeding device is capable of judging that a paper jam occurs on the basis of output from a first paper detecting switch and a second paper detecting switch. These paper detecting switches are respectively provided ahead of and behind a registration roller which feeds paper sheets to an image forming section. If the first paper detecting switch is turned on when a predetermined time has elapsed since the registration roller started to feed a paper sheet to the image forming section, it is judged that a duplicate paper feeding state has occurred where a plurality of paper sheets are simultaneously fed. If the second paper detecting switch is turned off in the case where it is judged that a duplicate paper feeding state has occurred, it is judged that a paper jam has not occurred. The registration roller is stopped so it will later be ready to feed the subsequent paper sheet. Even when the paper sheets are simultaneously fed in a duplicate paper feeding state, it is not judged that a paper jam occurs as long as the paper sheets are fed one at a time to the image forming section. However, if both the first and second paper detecting switches remain on after the predetermined time, then it is judged that a paper jam has occurred.

摘要： In a time period from the time point where the forward end of a paper sheet fed from a pair of paper separation rollers reaches a registration roller to the time point, where the registration roller is driven, when the load torque exerted on a forward roller is not less than second regulated torque, the transmission of power to the forward roller is released by a torque limiter provided for the forward roller. In this case, therefore, the force of paper feeding produced by the pair of paper separation rollers is regulated. Consequently, a suitable force of paper feeding can be applied to the paper sheet, thereby to make it possible to regulate the paper sheet straight in the direction of paper feeding as well as to prevent the paper sheet from continuing to be fed even if the amount of deflection of the paper sheet is saturated between the pair of paper separation rollers and the registration roller to prevent the paper sheet from being wrinkled.

摘要： An image forming apparatus including a transfer discharger. A sheet material after transfer is detached from a photosensitive drum by virtue of its stiffness and its own weight. The sheet material detached from the drum is guided by a guiding member. The guiding member is made of insulating material and provided with a plurality of ribs. A charge removing member is disposed on a downstream side of the guiding member. Charge removing action occurs over spaces between the ribs and charges on a rear surface of the sheet material are removed as the sheet material is being guided by the ribs. The guiding member may be formed of antistatic material in at least a part of it which comes into contact with the sheet material. Further, the guiding member may include assisting guide portions in at least some of the spaces between the ribs for guiding a receiving substrate such as a sheet material, an envelope, or the like to upper portions of the ribs.

摘要： A paper-discharge tray for an image-forming apparatus is adapted to hold paper discharged by a paper-discharging device arranged downstream of a fixing device in the image-forming apparatus. The free end of the paper-discharge tray is adapted to be bent in the direction in which the paper will curl when it passes through the fixing device, such that the paper can be stably stacked even when it curls during the fixing process.
