    • An image forming apparatus is provided which ensures proper image forming when the apparatus is positioned either horizontally or upright. The apparatus includes a rotary, endless latent image carrier, and a latent image forming arrangement for forming a latent image on the latent image carrier. The apparatus also includes a developing arrangement for developing the latent image on the latent image carrier by using powdered developer, and a transferring arrangement for transferring a developed image on the latent image carrier to a sheet. The apparatus further includes a positioning mechanism for selectively positioning the developing arrangement relative to the latent image carrier at one of a first position corresponding to an upright installation of the apparatus and a second position corresponding to a horizontal installation of the apparatus.
    • 提供了一种图像形成装置,当装置水平或垂直定位时,确保适当的图像形成。 该装置包括旋转式,环形潜像载体和用于在潜像载体上形成潜像的潜像形成装置。 该装置还包括用于通过使用粉状显影剂在潜像载体上显影潜像的显影装置和用于将潜像载体上的显影图像转印到片材上的转印装置。 所述装置还包括定位机构,用于相对于所述潜像载体选择性地定位所述显影装置,所述定位机构在对应于所述装置的直立安装的第一位置和对应于所述装置的水平安装的第二位置中的一个位置。

    • A developing device includes a magnet roll magnetized with plural magnetic poles including a main magnetic pole, a sleeve in a cylindrical shape which is arranged so as to be opposed to an image holding body, and a supporting frame that stably supports the magnet roll in a manner of restraining the magnet roll from rotating in the tangential direction, and supports the sleeve so as to rotate in the tangential direction around the magnet roll. The magnet roll is so arranged that the main magnetic pole is opposed to the image holding body, and a point on the peripheral face where magnetic flux density of the main magnetic pole in the tangential direction at a position along the peripheral face of the magnet roll is zero is set at a position predetermined with respect to a position where the magnet roll comes most closely to the image holding body.

    • A toner near empty discriminating unit discriminates a near empty indicating that the toner approaches an empty state on the basis of a detection value of a toner sensor. When the toner near empty is determined, a toner supply amount calculating unit calculates a toner supply amount (w) per time as w=W/X from the number (X) of toner supplying times of a toner supply counter and a specified toner filling amount (W) when a toner cartridge is set. On the basis of the calculated toner supply amount (w) of one time, a correction processing unit corrects a rotational speed of a supply roller of a toner supply control unit and an operation time of the supply roller, or the number of discriminating times of the toner empty and the number of discriminating times of a replacement of an expendable item.
