20090162088 | IMAGE FORMING APPARATUS AND FUSER UNIT CLEANING METHOD - An image forming apparatus includes a fuser unit that includes a first roller and a second roller opposite to each other, a first conveyance unit, a second conveyance unit, a drive unit, and a control unit to control the drive unit to rotate one or both of the first roller and the second roller in a state where a sheet contacts with the first roller and the second roller and the sheet is held by the first conveyance unit and the second conveyance unit, or in a state where after the sheet is held by the first conveyance unit and the second conveyance unit, one or both of the first conveyance unit and the second conveyance unit move in a direction of approaching at least one of the first roller and the second roller and the sheet contacts with the first roller or the second roller. | 2009-06-25 |
20090162089 | IMAGE FORMING APPARATUS AND METHOD OF CALCULATING AN AMOUNT OF TONER TRANSFER BY CONVERTING REGULAR REFLECTION OUTPUT INTO A NORMALIZED VALUE - An amount of toner transfer on a reference pattern is calculated by using an optical detecting unit that detects both regular reflection light and diffuse reflection light from a detection target simultaneously, based on a relative ratio between a value obtained by subtracting a result of multiplying a “diffuse reflection output” by a “minimum value of a ratio between a regular reflection output and the diffuse reflection output” from the “regular reflection output” of the density detection reference pattern, and a value obtained by subtracting a result of multiplying the “diffuse reflection output” by a “minimum value of a ratio between the regular reflection output and the diffuse reflection output” from the “regular reflection output” in the background of a transfer belt or an intermediate transfer body. | 2009-06-25 |
