An image forming apparatus can be achieved as, for example, a copying machine. The copying machine according to the present invention includes a handy scanner provided detachably from the main body of the copy machine and an additional data recording device for recording data read by the handy scanner as additonal data in addition to a mechanism for reading an image of a document disposed on an original glass plate to copy the same onto recording paper. The handy scanner can read arbitrary image data such as a figure, a designed character or a logotype. The image data read by the handy scanner is applied to the additional data recording device. If the paper on which the document image has been copied is provided to the additional data recording device, the additional data recording device records the additonal data at the rear of the paper on which the document image has been copied. The additional data recording device is operated after the document image is copied, the paper being conveyed at a speed different from that at the time of copying the document image.

A copying paper feeding device comprises a first and a second paper loading sections to be loaded with a stack of copying paper sheets, a first and a second paper delivery mechanism disposed respectively in the first and second paper loading sections, a first and a second paper introducing passage extending respectively from the first and second paper loading sections and terminating in a common point of junction, a paper conveying passage extending from the point of junction, a first conveyer roller pair disposed in the first paper introducing passage, and a second conveyor roller pair disposed at the point of junction or at an upstream part of the paper conveying passage. In performing a copying process, either the first or second paper delivery mechanism is selectively actuated. The first and the second conveyor roller pairs are interlocked with each other, and adapted to be started after the first or second paper delivery mechanism has been actuated. When the first paper delivery mechanism is selectively actuated, the roller pairs are started earlier by the time required to convey a copying paper from the first conveyor roller pair to the second conveyor roller pair than when the second paper delivery mechanism is actuated. The first conveyor roller pair exerts position-correcting and synchronism-adjusting actions on a copying paper delivered from the first paper loading section, and the second conveyor roller pair exerts position-correcting and synchronism-adjusting actions on a copying paper delivered from the second paper loading section.

A copying paper is deflected at least twice in the conveying process thereof from a paper feeding means to a photoreceptor which is disposed in the lower reaches of the conveying direction, whereby the positional state of the top edge of the copying paper is corrected at least twice. Since the extent of each deflection of the copying paper can be reduced, a habit of creasing, which has been a bad influence upon the transferring process, is not inflicted on the copying paper. The correction of the position of the top of the copying paper can be accurately carried out, whereby a clear image can be formed on the appointed position of the copying paper.

Copying machine

A method for controlling a copying machine having a copying cycle and fusing device. The fusing device is formed of a rotatable heating roller and a press roller in mutually forcible contact with the heating roller, which fuses a toner image on a copying paper at a fusing temperature upon passage through the rollers. The heating roller is heated to a first temperature above the fusing temperature. The copying cycle is delayed during a first interval of time after the heating roller reaches the first temperature. The copying cycle is set to a wait-reset state after the first time interval. The heating roller is cooled to a second temperature below the fusing temperature and the copying cycle is set to a wait state. The heating roller is heated from the second temperature to the fusing temperature during a second interval of time. The copying cycle is restored to the wait-reset state during the second time interval before the heating roller reaches the fusing temperature. The copying cycle is restored to the wait-reset state before a leading edge of the copying paper reaches the fusing device. In addition, the fusing device is at the fusing temperature when the leading edge passes between the rollers.
