摘要： A method of forming an electrostatic latent image includes printing operation and toner recovering operation. the printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

摘要翻译： 形成静电潜像的方法包括打印操作和调色剂回收操作。 打印操作包括充电，形成静电潜像，显影和转印操作。 调色剂回收操作包括以下步骤：在打印操作之后以与感光鼓的旋转定时关系的方式充电感光鼓，使得沉积在充电辊上的反向充电的调色剂从充电辊移动到感光鼓。 从充电辊迁移到感光鼓的调色剂被回收到显影剂中。 用于形成图像的装置包括充电辊，感光鼓，显影辊和转印辊。 该装置还包括一个反向充电的调色剂回收装置，其使打印操作之后使感光鼓以与感光鼓的转动成正比的方式进行充电，使得沉积在充电辊上的反向充电的调色剂迁移到感光鼓上。 显影剂从充电辊回收已经迁移到感光鼓的调色剂。

摘要： A ribbon protector is used for protecting paper from contamination by an ink ribbon in a printer, where the protector is inserted between paper located between a platen and a printing head. The printing head facing the platen performs spacing movement for printing. Two connected plate-like elements are provided with through openings for passage of the pin of the printing head. Mutually engageable electroconductive elements are provided on the inner walls of the two plate-like elements, at least in the area where they are compressed by the tip of the printing head, and spacers which are made from resilient materials are located between the two plate-like elements.

摘要： In a printer in which a printing medium is moved by a line-feed stepping motor during line-feed operation, and the line-feed stepping motor is stopped during printing operation and in a ready state, the line-feed stepping motor is caused to generate a first holding torque for preventing unwanted movement of the printing medium while permitting the operator to feed the printing medium manually, in the ready state of the printer, and the line-feed stepping motor is caused to generate a second holding torque which is greater than the first holding torque, during the printing operation.

摘要： A carriage mechanism of a printer includes a carriage frame, a printed circuit board mounted on the carriage frame and having an exposed wiring portion and a plurality portion of guide holes, and a cable having at one end thereof an exposed wiring portion to be electrically connected to the exposed wiring portion of the printed circuit board. An inked ribbon feed mechanism has guide projections to be inserted into the guide holes and a plurality of elastic hooks for fastening to the carriage frame. A cable fixing mechanism includes a flexible film member to be superimposed over the end of the flexible cable and fixed thereto. One end of the flexible film member is shaped as the end of the flexible cable and the other end of the flexible film member is progressively narrower and projects toward a folded portion of the flexible cable.
