摘要： A transfer roller is spaced away from the outer surface of a photosensitive drum by a specified distance to prevent the abrasion and damage of the photosensitive drum by the contact of the transfer roller and the photosensitive drum. The transfer roller not in contact with the photosensitive drum can be formed to have a sufficient hardness without damaging the outer surface of the photosensitive drum. Further, since the transfer roller has a sufficient hardness, cleaning blades can be held in without damaging the transfer roller with a sufficiently large force without damaging the transfer roller, thereby securely scraping off toner and the line adhered to the transfer roller and preventing the rear surface of a transfer sheet from being smeared.
摘要翻译：转印辊与感光鼓的外表面间隔一定距离，以防止感光鼓通过转印辊和感光鼓的接触而磨损和损坏。不与感光鼓接触的转印辊可以形成为具有足够的硬度而不损坏感光鼓的外表面。此外，由于转印辊具有足够的硬度，因此可以以足够大的力将清洁刮刀保持在不会损坏转印辊的同时不会损坏转印辊，从而可靠地刮除调色剂和附着在转印辊上的线，并防止转印辊的后部转印片的表面被弄脏。

摘要： An image-forming machine comprises a sheet member conveying passage extending through a transfer zone and a fixing zone, a sheet member-feeding means for feeding a sheet member onto the sheet member conveying passage, and a sheet member conveying means for conveying the sheet member through the sheet member conveying passage. A housing of the image-forming machine has a lower surface defined by an intermediate lower wall and an upper surface defined by an intermediate upper wall, and forms a space of which the front surface is opened. The downstream end portion of the sheet member conveying passage extends along a one side portion of the intermediate lower wall on the lower side thereof. The one side portion of the intermediate lower wall is defined by the opening/closing member, and opening/closing member is brought to the open position to open the downstream end portion of the sheet member conveying passage. The sheet member conveying means includes a pair of register rollers. After the leading edge of the sheet member delivered onto the sheet member conveying passage is brought into contact with the nip of the pair of register rollers, the pair of register rollers are preliminarily rotated for only a predetermined period of time.

摘要： A fixing device for image forming apparatus includes: a first nip member in a shape of an endless belt and a second nip member that rotates while pressed against the first nip member. A heat source heats at least one of the nip members. A pressure receiver receives pressure applied to the first nip member from the second nip member. A sliding contact has a contact surface that makes sliding contact with an inner surface of an axial end of the first nip member. A supporting mechanism supports the sliding contact to displace the contact surface thereof away from the pressure receiver as the first nip member moves away from the sliding contact along the axial direction. The displacement increases frictional forces between the contact surface and the inner surface of the first nip member, thus suppressing axial displacement of the first nip member from the sliding contact.

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.
