摘要： A developing device used in an electrophotographic apparatus has seal members fixedly disposed between both end portions of a developing roller and those portions of inner walls of a device casing which correspond to both end portions of the developing roller. The seal members are made of a material which can be charged by friction with the developing roller to have the same polarity as charged toner. The toner is blocked by the seal members and presented from entering end portions of the developing roller.

摘要： A transfer device of a contact transfer method wherein a transfer power supply applies a predetermined transfer voltage to a transfer roller contacting the rear surface of a printing sheet, so that an electric field for causing the toner to be attracted by the transfer roller is generated. A lumped constant resistor is electrically inserted between the transfer roller and the transfer power supply. The lumped constant resistor has an electric resistance smaller than an equivalent electric resistance obtained when the whole transfer roller is regarded as one electric resistor. When the electric resistance of the printing sheet changes in accordance with a change in ambient environment, the voltage drop across the lumped constant resistor is changed to compensate for the change in electric resistance of the printing sheet.

摘要： At start of rotation of a photosensitive drum, rotation of a developing roller caused by a developing/register rollers driver is kept stopped until a time required for a predetermined point on the photosensitive member, which was located at a charging position when charging thereof by a charging device was started, to reach a development position elapses, and thereafter the developing roller is rotated by the developing/register rollers driver. When the predetermined point on the photosensitive member, which was located at the developing position when at least rotation of the photosensitive member was started, passes the transfer position, a roller cleaning voltage having the same polarity as the charge polarity of toner is applied to a transfer roller.

摘要： In a developing device for developing an electrostatic latent image formed on a photosensitive member in an electrophotographic apparatus, a developing roller and a developing blade are formed such that the hardness of the surface of the developing blade is higher than the hardness of the surface of the developing roller by 30 degrees or more in JIS-A hardness. The developing blade deforms and bites into the developing roller. Accordingly, the developing roller can be brought into tight contact with the developing blade, and a great frictional force is applied to the toner passing between the developing roller and blade to fully charge the toner.

摘要： A toner pack for use in an electrophotographic apparatus is formed of a polypropylene resin containing 30 to 50 wt % calcium carbonate filler. This resin has a high deformability, and generates a small amount of heat at the time of incineration thereof. Thus, the used toner pack can be disposed of together with flammable products made of paper and/or wood. Further, at the time of disposal, it is possible to fold the used toner pack to reduce its size.

摘要： To prevent spurious adherence of toner to the surface of a photosensitive drum during start-up of an electrophotographic printing apparatus, once rotation of the drum and charging of the drum surface to a predetermined potential are initiated, rotation of a developing roller to bring toner into contact with the drum surface is delayed until the charged portion of the drum surface has been rotated around to a position facing the developing roller. Applications of appropriately timed biasing voltages to the developing roller and an image transfer roller are also utilized to prevent spurious toner attraction to the surfaces of the drum and the transfer roller.

摘要： A transfer unit has a plastic end block at each end. The end block includes a bearing for supporting an auxiliary roller, and an arm having at its end portion a pivot received by a lower casing. The bearing and the arm are formed integrally with the end block. A leaf spring located under the transfer unit supports it along with the roller in movable relationship around the pivot. When an upper casing is shut down, a photoreceptor drum supported in the upper casing pushes down the transfer unit against the elastic force of the leaf spring. Since the positions of the transfer unit and the roller are determined with respect to the photoreceptor drum, good duplicativity can be obtained. In this state, a cylindrical spacer serves to secure a predetermined space between the photoreceptor drum and the auxiliary roller.
