摘要： An image-forming apparatus includes an image-forming section, a detection section, and a controller. The image-forming section has an image-bearing body on which an electrostatic latent image is formed and a developing unit that develops the electrostatic latent image. The detection section generates an output indicative of a remaining amount of toner in the developing unit. The controller drives the drive section to cause the image-forming section to move from one position to another, and determines a position of the image-forming section based on the output of the detection section. The detection section is mounted to a toner cartridge within the developing unit. When the image-forming section is moved from one position to another, the detection section receives light reflected by a high-reflectivity area and a low-reflectivity area, thereby detecting the position of the image-forming section.

摘要： A color image recording apparatus includes a mechanism that switches a plurality of image forming sections between image forming positions where the photoconductive drums are in contact with a transport belt and non-image forming positions where the photoconductive drums are not in contact with the transport belt. A pair of slide links extend and are slidable in a direction in which the image forming sections are aligned. Each of the slide links has first guide surfaces and second guide surfaces. When the image forming sections are at the image forming positions, supporting shafts of corresponding one of image forming sections rest on the first guide surfaces. When the image forming sections at the non-image forming positions, the supporting shafts of corresponding one of image forming sections rest on the second guide surfaces.

摘要： A color image forming apparatus provides the prolonged life of the photosensitive drums, carrier belt, and toner of the respective colors and improves the quality of the printed color image. A carrier belt transports a recording medium placed thereon so that the recording medium passes through a plurality of printing mechanisms which print images of different colors on the recording medium in superposition. Each printing mechanism prints an image of a corresponding color. The printing mechanism is adapted to be moved into its operative position where the photosensitive drum of the printing mechanism is in contact with the carrier belt to print the image on the recording medium, and into its non-operative position where the photosensitive drum of the printing mechanism is not in contact with the carrier belt. A controller receives print data from a host device such as a personal computer and checks each page of the print data to determine whether any one of a predetermined plurality of colors is missing in the page. If a particular color is missing in the print data, then the controller outputs an UP signal to a positioning mechanism for a corresponding printing mechanism. If the color is not missing, then the controller outputs a DOWN signal. The printing mechanism moves a corresponding printing mechanism into the operative position if the UP signal is received from the controller and into its operative position if the DOWN signal is received.

摘要： A toner image fixing device in an electrophotographic image forming apparatus has a heating roller containing a heater and a backup roller, a surface of which is in contact with a surface of the heating roller. A toner image on the paper is fixed by causing the paper to pass through a contacting portion of the heating roller and the backup roller. The toner image fixing device also has a driving device for supplying driving power to the heating roller or the backup roller to rotate both the heating roller and the backup roller, and a controller. The controller controls the driving section in such a way that both the heating roller and the backup roller begin to rotate intermittently immediately after an electric power supply switch of the apparatus is turned on and heat generation from the heater is initiated, and subsequently begin to rotate continuously when the backup roller achieves one revolution by the intermittent rotation. Alternatively, the rotation speed of the heating roller and backup roller is gradually and continuously increased immediately after electric power is initiated and subsequently reach a constant speed.
