摘要： According to an embodiment of the invention, degradation of carrier in a case is detected from the number of rotations of a developing roller. A predetermined quantity of carrier is replenished every time the developing roller reaches a predetermined number of rotations. An excess developer caused by an increase in bulk through carrier replenishment is discharged from a developer discharge port. The degraded old carrier in the case is replaced by new carrier little by little.

摘要： A constant current output is applied to a backup roller or a secondary transfer member, and a cleaning bias is controlled according to a measurement obtained by monitoring a voltage generated at that time. Cleaning biases of a plus polarity and a minus polarity are alternately applied to the backup roller to recover the toner adhered on the secondary transfer member to an intermediate transfer belt. The cleaning bias is controlled according to the combined resistance of a secondary transfer section which is varied with not only the environment of an image forming apparatus, but also the condition of use and various factors to recover the toner adhered to the secondary transfer member to the intermediate transfer belt without fail, thereby preventing smudges on the back of a sheet of paper or smudges on images.

摘要： Hydrogen-rich reformate gas is produced by a fuel reformer (2) from fuel vapor containing hydrocarbon, which is produced by a fuel vaporizer (6), by means of a partial oxidation reaction and a steam reforming reaction. A fuel injector (8, 9) supplies fuel to the fuel vaporizer (6), and an air injector (8a) supplies air to the fuel vaporizer (6). A glow plug (13) partially oxidizes the air-fuel mixture inside the fuel vaporizer (6). By controlling the air supply amount in relation to the fuel supply amount to obtain an excess air factor corresponding to a predetermined rich air-fuel ratio, a part of the air-fuel mixture in the fuel vaporizer (6) is partially oxidized, and the remaining fuel vapor is heated by the oxidation heat. As a result, the partial oxidation reaction and steam reforming reaction in the fuel reformer (2) are performed with a favorable balance.
