Abstract: An apparatus for reading a radiographic image is provided with a holding section for holding a medium taken out from a cassette, wherein the medium has a recording surface on which the radiographic image is stored, the hold section holding the medium such that the orientation of the recording surface is substantially vertical; and a reading section for reading the radiographic image on the recording surface of the medium held by the holding section, thereby obtaining radiographic image information from the recording surface.

Abstract: A cassette in which a radiographic image converting plate is accommodated, comprises a case having an opening; a tray on which the radiographic image converting plate is loaded; and a cap capable of being fitted with the opening, the cap connected with the tray so that the tray is moved together with the cap so as to be inserted into or drawn out from the case through the opening, the position of the cap capable of being displaced relative to the tray.

Abstract: Disclosed is an apparatus for forming a color image on a photoreceptor, in which along the rotation direction of the photoreceptor there are provided an imagewise exposure process to form a latent image, a development process including a plurality of developing devices to form a color toner image, each of the plural developing devices having a toner hopper, and a transfer process to transfer the formed color toner image onto a copy paper. The apparatus comprises a housing for including at least the photoreceptor, the plural developing devices and the plural toner hopper as one unit, and a support guide for supporting the housing to be movable in the axial direction of the photoreceptor so that the unit is attached to and detached from the apparatus.

Abstract: A multicolor image forming apparatus wherein a plurality of developing devices for forming a multicolor image are integrally supported by a support member which can be inserted into and withdrawn from an apparatus body, and a plurality of resupply devices for replenishing toner particles are mounted on each of the developing devices. Each of the developing devices and each of the resupply devices corresponding to each of the developing devices are automatically connected to and disconnected from each other, when the support member is inserted into and withdrawn from the apparatus body. The support member further supports an image retainer and if necessary a cleaning member integrally.

Abstract: A color image forming apparatus having a photosensitive drum and a plurality of developing devices. The developing devices are accommodated removably in an integral casing. The integral casing can be held in a fixed position with respect to the photosensitive drum and moved apart from the photosensitive drum. The developing devices can be mounted independently of one another in an adjustable manner or mounting reference members respectively, which are mounted in the integral casing.

Abstract: An image forming apparatus having a cleaning device arranged on the outer periphery of an image retainer, and bringing into and out of abutment against the image retainer, wherein the cleaning device comprises a first cleaning member and a second cleaning member arranged downstream of the first cleaning member in the moving direction of the surface of the image retainer. A cleaning operation of the second cleaning member against the image retainer is conducted according to a time at which the cleaning operation of the first cleaning member against the image retainer is conducted.
