A toner cartridge mountable to a cartridge mount of a main assembly of an image forming apparatus comprising an electrostatic latent image bearing member, and a toner container for containing toner for developing an electrostatic latent image on the image bearing member, wherein the cartridge is disposable in a mounting position, where the toner cartridge can be mounted on or dismounted from the cartridge mount, and a toner supply position, where toner can be supplied into the container from the toner cartridge. When toner is to be supplied into the container, the toner cartridge is rotated in a predetermined direction from the mounting position to the supply position, and when the toner cartridge is to be dismounted from the cartridge mount, the toner cartridge is rotated in the opposite direction. The toner cartridge includes a container body for containing the toner, and a toner discharge opening is provided in the container body for discharging toner from the container body. A shutter opens and shuts the discharge opening. A shutter support supports the shutter for movement between a closed position and an open position. A projection located at a corner portion of the support is engageable with an engaging portion of the cartridge mount, wherein when the toner cartridge is at the toner supply position, the projection is engaged with the engaging portion to prevent removal of the toner cartridge from the cartridge mount.

Print jobs having a mixture of first image sheets and second image sheets are sorted to a first image forming device and a second image forming device. After image formation is performed on sheets by the respective image forming devices, radio frequency IC tags (RFID tags) are affixed to the sheets, in which attribute information including post-processing information and page identification information is written. Sheet bundles produced by the respective image forming devices are separately set to a post-processing device. The post-processing device reads out the attribute information stored in the radio frequency IC tags, and the sheets are selectively fed from the respective sheet bundles while conforming to the page order. Thereafter, the post processing is performed.

In a cathode-ray tube apparatus, a deflection yoke is provided on a funnel of a tube and a pair of closed loop coils are provided on a panel and the funnel of the tube at upper and lower sides, respectively. The deflection yoke generates effective magnetic fluxes in the tube and also generates ineffective magnetic fluxes as leakage magnetic fluxes outside of the tube. Some of the leakage magnetic fluxes pass through the coils so that currents are induced in the coils and the resulting induced magnetic fluxes compensate for the leakage magnetic fluxes. Thus, the leakage magnetic fluxes passing through a space in front of the tube are reduced by the compensating magnetic fluxes from the coils.

In a cathode ray tube apparatus, a deflection yoke for generating an effective magnetic field to deflect electron beams in an envelope is provided around a funnel of the envelope. A pair of front magnetic coils are in substantially symmetrical with respect to a horizontal plane including a tube axis and a horizontal direction and are provided on a skirt of the envelope. A pair of rear magnetic coils are also arranged in substantially symmetrical with respect to the horizontal plane and are provided on the deflection yoke. Leakage magnetic fluxes generated from the deflection yoke are reduced by compensating magnetic fluxes generated from the front and rear magnetic coils.

To remove also VOC gas generated from the discharged sheets, an image forming apparatus comprises an image forming unit which forms an image on a sheet; a tray on which sheets on which images are formed by the image forming unit are stacked; a suction device which sucks air from the surrounding space of sheets stacked up on the tray; and a VOC removing unit which removes VOC contained in the air sucked by the sucking device.

If a next endpoint in a line segment is determined to be neither in a first nor a second reference direction passing through a base endpoint, a point obtained by projecting the next endpoint onto a straight line in the first reference direction passing through the base endpoint or a straight line in the second reference direction passing through the base endpoint is set as a correction endpoint. If the next endpoint is determined to be in the first or second reference direction passing through the next endpoint, the next endpoint is set as a new base endpoint. If the next endpoint is determined to be in neither the first reference direction passing through the base endpoint nor the second reference direction, the correction endpoint is set as a new base endpoint. Each endpoint of the plurality of line elements is subjected to the above process so as to generate a simplified shape.
