    摘要： In an image forming apparatus using a transfer unit of a roller transfer method, the contact between the transfer unit and a photoreceptor drum can easily be canceled. The transfer unit is brought into contact with the photoreceptor drum by supplying an upward pushing force to a supporting member of the transfer unit, and a lever engaging with the supporting member to push down the supporting member is provided to connect with a front cover of the apparatus body. The transfer roller, the pre-transfer roller for feeding a sheet to the photoreceptor drum and driving force transmitting gears provided therebetween are supported by the same member to fix their relative positions so that the driving force is constantly transmitted from the transfer roller to the pre-transfer roller.

    摘要： In a transfer unit of a non-contact roller transfer method, both ends of a transfer roller shaft are supported independently of each other so as to be movable upward and downward, and an upward pushing force is provided thereto. A gap maintaining roller provided in the vicinity of each end portion of the transfer roller shaft is always in contact with the surface of a photoreceptor drum so that the gap between the surface of the photoreceptor drum and the transfer roller is maintained uniform and fixed. Further, both ends of a pre-transfer guide for guiding the sheet to the photoreceptor drum are supported in a manner such that the movement of each end accords with the movement of the end portion of the transfer roller, so that the distance between the photoreceptor drum and the pre-transfer guide is maintained uniform and fixed.

    摘要： If it is desired to display the number of copies which can be outputted corresponding to the defined capacity of a developer which is determined by an image forming apparatus, a document which is thought to have a substantially average black ratio of the respective black ratios of images actually recorded by the image forming apparatus is prepared. The prepared document is set in reading means. An image of the set document is read by reading means. The black ratio of the image of the document is calculated on the basis of an output of the reading means. The number of copies which can be outputted corresponding to the defined capacity of the developer which is determined by the image forming apparatus is calculated on the basis of the calculated black ratio. The calculated number of copies which can be outputted is displayed.

    摘要： A transferring apparatus transfers a toner image formed on the surface of a photoreceptor drum onto a sheet. The photoreceptor drum surface and a transfer roller are arranged in such manner that a gap larger than the thickness of the sheet is left between the photoreceptor drum and transfer roller, and a lower guide member for guiding the sheet in such direction that the sheet abuts the drum surface at a predetermined angle is arranged between a resist roller pair and the drum. The sheet which abuts the drum surface by way of the upper surface of the guide member is in close contact with the drum surface while being bent and deformed along the drum surface. A conveying roller is provided, opposite the upper surface of the lower guide member, with a predetermined gap between, at a position close to but out of contact with the drum surface. The conveying roller may also be arranged to contact the transfer roller.

    摘要： A developing unit comprises a developer container having an agitation space for agitating developer therein and a toner hopper for feeding toner to the agitation space of the developer container. A lower wall of the toner hopper includes a toner drop port allowing toner to fall into the aforesaid agitation space. On a surface of the lower wall exposed to the agitation space, disposed is a partition wall surrounding the periphery of the toner drop port. The partition wall defines a non-agitation space. The toner is allowed to fall from the toner drop port smoothly into the agitation space through the non-agitation space which is not affected by the agitation.

    摘要： A supporting and driving mechanism including a rotatable body and a supporting unit for assuring stable support and rotation of the rotatable body for a long time. The mechanism includes an axis member at either end of the rotatable body, a driven gear at one end of the rotatable body, two rollers and a driving gear of the supporting unit. The two rollers are placed parallel to each other and the distance between the closed surfaces of the rollers is smaller than the diameter of the axis member of the rotatable body. The driving gear engages the driven gear and transmits a driving force to the driven gear of the rotatable body. The driving force applied from the driving gear to the driven gear directs between the centers of the two rollers when the driving force is translated so that the origin of the force is brought to the center of the axis member of the rotatable body. Thus the axis member is pressed toward the two rollers while the rotatable body is driven by the supporting unit, whereby the position of the axis member is fixed and the stable rotation of the rotatable body is assured for a long time.
