摘要： A projecting tab formed with a bulged portion and an indent on an upper side thereof is provided inwardly projecting in a transport path. A sheet being transported in the transport path is formed into a seemingly wavy configuration in the width direction of the transport path while in contact with the projecting tab. The sheet thus formed with the seemingly wavy configuration is given with a sufficient transport backup force in a transport direction, thereby being hard to bend in the transport direction. Thus, the sheet supplied with the sufficient transport backup force is free from a curled lead end, folded or bent corner lead end of the sheet in the transport direction, and sheet jam. The arrangement of the projecting tab securely accomplishes sheet transport in a desired transport direction without a possibility of sheet transport failure.
摘要翻译：在输送路径中向内突出形成有凸出部分和在其上侧的凹口的突出突片。在传送路径中传送的片材在与突出片接触的同时在传送路径的宽度方向上形成为看似波状的构造。由此形成为具有看似波状构造的片材在输送方向上具有足够的输送支撑力，因此难以在输送方向上弯曲。因此，具有足够的传送支撑力的片材在传送方向上没有卷曲的引线端，片材的折叠或弯曲的尖端，并且卡纸。突出片的布置牢固地在期望的输送方向上实现片材输送，而不会造成片材传送失败。

摘要： In a paper transport device, a first roller serving as a separation roller is situated underneath a second roller serving as a document feed roller, together forming a roller pair. A rotary shaft of the separation roller is biased upward toward the document feed roller by means of an elastic element. One end of the rotary shaft is connected to a drive shaft via a coupler while a connecting bar is joined to the other end of the rotary shaft obliquely from above. An extreme end of the connecting bar opposite to the rotary shaft is attached to a support plate fixed to a main body of the paper transport device in such a way that the connecting bar can swing about pivot pin fixed to the support plate. In the paper transport device thus constructed, one end of the rotary shaft fitted to the coupler acts as a point of support, allowing the other end of the rotary shaft to move downward overwhelming an upward-lifting force of the elastic element when forced downward by the connecting bar. In this construction, the separation roller can be separated from and brought into contact with the document feed roller.

摘要： A sheet transport device is provided with a sheet inverting mechanism for performing a switchback operation in which a sheet transported along a main transport route enters a switchback route, and the sheet transport direction is inverted in the switchback route to return the sheet to the main transport route so as to turn the side of the sheet. A registration roller pair is disposed near the junction between the main transport route and the switchback route. The sheet inverting mechanism is operated in such a manner that the sheet transport is temporarily suspended until a skew correctable portion that enables correction of a skew transport state of the sheet is formed at a lead end of the sheet in the exiting direction from the switchback route after the lead end of the sheet comes into contact with the registration roller pair. Thus, the skew transport state of the sheet which is liable to occur during the switchback operation is corrected.

摘要： A recycle developing method utilizes the steps of (1) providing a developing vessel containing a starting developer composed of an electroscopic toner and a magnetic carrier; (2) transferring toner from the developing vessel to a photosensitive material having an electrostatic latent image formed thereon; (3) transferring a portion of the toner on the photosensitive material to a paper to form a toner image on the paper; (4) recovering toner remaining on the photosensitive material after the aforementioned portion of toner is transferred to the paper to form a toner image thereon; and (5) repeating steps (2)-(4) while replenishing toner in the developing vessel by the sub-steps of: (5a) supplying toner recovered in step (4) to the developing vessel, and (5b) supplying a virgin toner, having a higher chargeability than the electroscopic toner in the starting developer, to the developing vessel, to form a mixed toner in the developing vessel. An absolute value of the average charge quantity of the mixed toner is greater than the absolute value of the average charge quantity of the electroscopic toner in the starting developer plus 10 .mu.C/g. Apparatus to effect the process is also disclosed.
