A method of forming an electrostatic latent image includes printing operation and toner recovering operation. the printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

A fusing apparatus 14 for fusing toner onto paper includes a heater roller 2 and a separating unit 15 with a separation claw 16. The separation claw 16 is provided with a paper guide member 17 having a curvature in a direction opposite to the curvature from a point a to a point c on the heater roller 2. After fusing, the front end 10a of the separated paper 10 is guided by the paper guide member 17. The paper guide member 17 reforms a curl imparted by the heating roller 2 curl into the original state, even if the paper 10 sticks to the heater roller 2 until the point c.

A database management system is provided for protecting data from being malicious update or deleted. The system is arranged to hold as a table attribute an insert-only attribute and a row deletion prohibition period, and as an access right attribute a row insertion date and time holding column name and to specify a row insertion date and time when a row was inserted, for disabling said date and time data. When requesting a table data update or a row deletion, the table attribute and the row insertion date and time are checked for preventing the malicious update and deletion.

The efficiency of development of an application program constructed of a plurality of application windows utilizing GUI controls is improved. By causing a GUI control property defining information selector to select GUI control property defining information defined by a GUI control property defining information definer, the selected GUI control property defining information is reflected upon the property of a GUI control used in an application window editor. When the GUI control property defining information is changed by the GUI control property defining information definer, GUI control information in synchronism with the changed GUI control property defining information is searched from GUI control information used in the application window editor and GUI control property defining information after changing is reflected upon the searched GUI control property information.

A printer comprises a first paper feed passage extending from the rear of a platen to a printing position through the lower part of the platen, and a second paper feed passage extending from substantially just under the printing position to the printing position. A first pinch roller is disposed on the way to the first paper feed passage for pressing a first paper against the platen. The first paper is fed by rotating the platen. A second pinch roller is disposed on the way to the second paper feed passage for pressing the second paper against the platen. Rotation of the platen here causes the second paper to be fed. In addition, a paper insertion device according to the present invention includes a flat part for placing a paper thereon and a slit for converting the advance direction of a paper from horizontal to vertical. With the second paper placed on the flat part and inserted into the printer, the paper is directed upward after the curved surface of the slit and allowed to enter the second paper feed passage with ease for further advance.

A disk volume access controlling method includes the steps of setting a threshold number of times of accesses from a computer to a predetermined disk volume per time unit, acquiring a number of times of accesses to the predetermined disk volume per time unit, seeking whether or not the number of times of accesses acquired exceeds the threshold number of times, creating a mirror volume for the predetermined disk volume in case that the number of times of accesses acquired exceeds the threshold number of times, and changing an access pass between the computer and the predetermined disk volume to another access pass between the computer and the newly created mirror volume. It then becomes possible to distribute accesses to a certain disk volume, and further to make the accesses to a plurality of volumes even.

A continuous sheet guide mechanism for a printer having a rotatable cylindrical platen and a bottom guide plate disposed below the cylindrical platen forming a sheet guide path therebetween as well as a sheet inlet opening and a sheet outlet opening, a sheet guide plane formed upstream of the bottom guide plate for guiding a sheet into the sheet inlet opening and a pair of tractor units provided near the sheet outlet opening, the tractor units being supported on a fixed support shaft disposed near and parallel to the platen, and on a driving shaft for driving the tractor units, extending parallel to the support shaft. A sheet guide member is slidably mounted on the fixed support shaft and rotatably mounted on the driving shaft, the sheet guide member being composed of an upper gide wall for guiding the continuous sheet wound around the platen, a guide leg depending from the upper guide wall and having an inclined section forming an obtuse angle with the sheet guide plane so as to guide the continuous sheet downward toward a space below the platen and allow the sheet to be wound correctly around the platen. The guide leg includes a supporting section defining a recess which engages the driving shaft and a front end of the supporting section is rounded for guiding the sheet in the upward and reverse directions. The guide mechanism can include a paper separator for separating a sheet being guided from the printer.
