Title: Image forming method
Inventor: MIURA MASAHARU
IPC: G03G15/08
Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To provide an image forming method which can carry out stable electrostatic charging for a long period even when high-ratio images are continuously outputted by preventing a photosensitive body from having a defective electrostatic charging. SOLUTION: In a pre-rotation processing carried out prior to image formation, the photosensitive body 1 and a roller electrostatic charger 3 begin to be driven and at this time, an electrostatic charging roller is rotated at a rotating speed for discharge mode which is faster than that in normal image formation. It is confirmed that untransferred toner is discharged from the roller electrostatic charger. As the rotating speed of an electrostatic charging member is increased, the change to discharge the untransferred toner per unit time increases, so that the discharge efficiency of toner ticking on the electrostatic charging roller is improved. In the pre-rotation for image formation, a rotating speed having a 150% circumferential speed ratio to the circumferential speed of the photosensitive body is set as the discharge mode for image formation.  After the pre-rotation, the rotating speed of the electrostatic charging roller is lowered to a 40% circumferential speed ratio for the image formation.

Filed: 2001-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the seizure of a high pressure pump in an extremely low speed region while allowing normal operation to some extent during a failure in an electric system for a solenoid valve. SOLUTION: The common-rail fuel injection control device for allowing the forcible feed to a common rail 2 of a fuel supplied from a feed pump 6 and pressurized by the high pressure pump 3 and controlling the amount of the fuel to be supplied to the high pressure pump 3 with the normally opened solenoid valve 7 comprises fuel supply shut-off means 60 for mechanically shutting off the supply of the fuel to the high pressure pump 3 until the feeding pressure of the feed pump 6 reaches a preset value or more during deenergizing the solenoid valve.  During deenergization due to the failure in the electric system for the solenoid valve 7, when an engine speed is low down to the extremely low speed region and the feeding pressure of the feed pump 6 is less than the preset value, the fuel supply to the high pressure pump 3 is mechanically shut off and so the pressure pump 3 is in a non-forcibly-fed condition which precludes the operation of a high pressure on the pressure generating part thereof. Thus, the seizure of the high pressure pump 3 is prevented.
