摘要： In order to prevent toner leaks from both ends of a developing roller disposed within a case accommodating polymerized toner, side seals each having a TEFLON® (polytetrafluoroethylene) felt member on its surface are provided to make sliding contact with a surface of the developing roller. To prevent toner leaks from the ends of the developing roller, a film or resin stopper is disposed at a lower-end front edge of the case to oppose the felt members and to stop the toner.

摘要： A developing device for developing a latent static-electric image into a visible image from developer. Various members for preventing toner leaks are attached to the developing case. A lower-edge leak prevention member is attached below the developer bearing body. End leak prevention members are attached on either side of the lower-edge leak prevention member, near lengthwise ends of a developer bearing body. Portions of the developing case where the end leak prevention members are attached, are indented lower than the portion where the lower-edge leak prevention member is attached. Resilient foam members are attached an the same surface as the lower-edge leak prevention member, with one side surface in contact with one side surface of the corresponding end leak prevention member.

摘要： A layer thickness regulating blade 64 has a plate spring 64b and a pressing number 64a fixed thereto. The plate spring 64b is formed longer than the pressing member 64a so that both ends of the plate spring 64b are exposed. A front surface resilient foam seal 112 made from sponge is attached to the exposed portions, in contact with sides of the pressing member 64a. Further, a Teflon™ film 113 is attached on the plate spring 64b so as to cover the front surface resilient foam seal 112. A sponge side seal 111 is adhered to the rear surface of the plate spring 64b. A sponge side seal 107 is adhered to the developing case 51 at a position that confronts the blade side seal 111. An end seal 106 is adhered across a step portion E of the developing case 51 and the upper end of the base seal 104, and can compressing deform with the blade side seal 111 and the upper side seal 107.

摘要： In order to prevent toner leaks from both sides of a developing roller disposed within a case accommodating polymerized toner, side seals each having a TEFLON® (polytetrafluoroethylene) felt member on its surface are provided to make sliding contact with a surface of the developing roller. In addition, “Hanarl FL-Z75” (80-90 wt. % hydrofluorocarbon and 10-20 wt. % polytetrafluoroethylene) manufactured by Kanto Kasei Ltd., is used as a lubricating agent for the TEFLON® felt members to make them more lubricative. Accordingly, noise generated by the side seals sliding contact with the developing roller can be reduced. To prevent toner leaks from the sides of the developing roller, a film or resin stopper is disposed at a lower-end front edge of the case to stop the toner.

摘要： During printing on a thick paper, a Scorotron charger disposed upstream of a developing roller in a drum rotational direction charges a photosensitive drum to about 1000 V. Then a transfer roller disposed downstream of the developing roller lowers the potential to about 80 V. The transfer bias is turned off at the end of printing at T1 and does not lower the surface potential after this. When the surface of the drum opposite the transfer roller reaches a position opposite the Scorotron charger at T2, a DC motor and a charging bias are turned off. The surface potential of the drum that passes opposite the developing roller remains at about 400 V and is higher than developing roller potential until the photosensitive drum comes to a complete stop after idling at T3. This prevents the developing agent from adhering to the photosensitive drum.
摘要翻译：在厚纸上打印时，设置在鼓旋转方向上的显影辊上游的Scorotron充电器将感光鼓充电至约1000V。然后，设置在显影辊下游的转印辊将电位降至约80V。转印偏压在T 1打印结束时关闭，此后不会降低表面电位。当转鼓对面的表面在T 2处到达与Scorotron充电器相对的位置时，DC电机和充电偏压被关闭。与显影辊相对的鼓的表面电位保持在约400V，并高于显影辊电位，直到感光鼓在T 3空转之后完全停止。这防止显影剂粘附到感光鼓上。

摘要： In a transfer device, a flexible guide plate is disposed in a position upstream relative to a transfer position along a medium conveyance path, such that a first side of the guide plate faces to a recording medium being conveyed along the medium conveyance path. The guide plate has a downstream end portion that is angled by bending the guide plate. A support frame supports an upstream end portion of the guide plate and extends in a downstream direction beyond the downstream end portion to form an extension portion which is disposed opposite to a second side of the guide plate and toward which the downstream end portion extends obliquely downstream. The extension portion has a recess/hole formed in a position separated in an upstream direction from a first edge of the extension portion, to allow the downstream end portion to be moved without being blocked by the extension portion.
