A developer for electrophotography comprises toner particles and carrier particles. The carrier particles comprise at least two kinds of carriers particles having different charge giving characteristics onto the toner particles. Plural kinds of carrier particles having different charge giving characteristics act on one another and on the toner particles.

Developing method and a developer for electrophotography

In a copying machine, an original which has been once exposed to be scanned is inverted and transmitted again to an original table glass, and a sheet having one face onto which an image has been fixed is inverted and then transmitted through a transmitting path to an image forming section, whereby the top and back faces of the original are copied to the top and back faces of the sheet, respectively.

Copy machine having plural trays each tray capable of storing two

A sheet feeding apparatus which is used for front-loading type copy machines and the like, adapted to store laterally two kinds of sheets either of different sizes and/or of different storing directions in one cassette. The two kinds of sheets are taken out selectively and separately and fed to the copying machine assembly. In a preferred embodiment, the two kinds of sheets are stored in a storing device and each kind is taken out from an opposite side thereof. The sheet-feeding apparatus when used with an image forming apparatus provides for multifunctions such as multiple copying and double-face copying.

Sheet-feeding apparatus having sheet storing means with sheet removal

A copy system includes a combination of a tablet and an input pen for inputting copy condition information such as a control condition and an editing condition, and a copying machine for forming a copy image in accordance with a copy condition information as inputted. An IC card insertion portions are respectively formed on the tablets and the copying machine. When the control condition, for example, a copy quantity and a copy magnification, and the editing condition, for example, an editing function and a positional data are inputted by the input pen and the tablet in the state where the IC card is loaded to the tablet, the inputted copy condition information is stored in the IC card. Thereafter, the IC card is unloaded from the tablet and inserted to the copying machine. The copy condition information is led from the inserted IC card to the copying machine. Upon an operation of a start key, a copy image of an original put on an original table is formed in accordance with the copy condition information read out from the IC card.

Copy system

An apparatus for inputting image forming condition includes a combination of a tablet and an input pen. An IC card insertion portion is formed on the tablet. In the state that an IC card is loaded to the tablet, when a control condition, for example, a copy quantity and copy magnification and/or an editing condition, for example, editing function and positional data are inputted by operating the tablet by means of the input pen, the inputted image forming condition is stored into the IC card. Thereafter, by unloading the IC card from the tablet and loading the same into a copying machine, a copying image of an original is formed by the copying machine in accordance with the image forming condition read out from the IC card.

Apparatus for inputting image forming condition

An apparatus for inputting image forming condition includes a display having item displaying portion in which a plurality of items of image forming condition for controlling image forming process are respectively displayed for each item and cursor displaying portion in which a plurality of cursors are formed so as to correspond to the respective items. A desired one of a plurality of cursors included in the cursor displaying portion is selectively displayed by a cursor key. When a given item is designated by the cursor key and a change key is operated in that state, content of that item is changed for every operations of the change key. The content lastly changed is inputted as image forming condition of that item.

Electrostatic copying machine having removable paper path

A motion picture projector in which projector mechanisms are incorporated in the body of a carrying case, the opening of which is covered by a panel structure on which a reel setting portion and an operation board are disposed. The panel structure is provided with a projection window through which a light beam from the projector mechanisms is projected. A cover attached to the case body by hinge means is provided in the inside thereof with a rear-projection screen assembly, which is adapted to engage the case body and to be supported in a predetermined angle together with the case cover when unfolded. A light beam from the projection window is reflected by a mirror disposed in the inside of the case cover so as to be projected on the screen assembly. A projector in accordance with the present invention is formed in a readily portable shape and has high versatility because films wound upon usual open-type reels are available. In addition, the projected image is easy to see because of the large screen size. A generally available attache case can be used instead of a specially designed case, and the use of such ready-made case results in a reduced manufacturing cost. High operation efficiency is also expected.
