摘要： An image forming apparatus that transfers a toner image from includes a transfer belt to a sheet via to carry a toner image, a transfer roller. The image forming apparatus transfers the toner image by applying a transfer bias voltage to either the transfer roller or to make contact with the transfer belt to transfer the toner image onto a sheet from the transfer belt, an opposite roller facing the transfer roller across the transfer belt. The transfer bias voltage is decided by adding a transfer roller correction voltage, based on a voltage detected by a voltage detection unit when a predetermined current is applied to either the transfer roller or the opposite roller by a current application unit when no sheet is present in a transfer position, and a sheet correction voltage, based on a sheet kind and an intra-apparatus humidity.

摘要： According to the invention, a constant current output is applied to a backup roller or a secondary transfer member, and the cleaning bias is controlled according to the measurement obtained by monitoring the 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 roller to the intermediate transfer belt. The cleaning bias is controlled according to the combined resistance of the secondary transfer section which is varied with not only the environment of the image forming apparatus, but also the condition of use and various factors to recover the toner adhered to the secondary transfer roller to the intermediate transfer belt without fail, thereby preventing smudges on the back of sheet paper or smudges on images.

A gas mixture obtained by mixing a to-be-combusted gas with a combustion-assisting gas is supplied to a heating passage 25 in the heating layer 3. The heating passage 25 is separated into multiple separation passages 31a to 31c by separation walls 11, 13 parallel to a wall surface coated with the combustion catalyst 8. The multiple separation passages 31a to 31c respectively eject the gas mixture to different positions of the combustion catalyst 8.

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.
