The voltage supply unit varies the voltage supplied to the transfer member, either before or after or both before and after the developing agent images are transferred from the intermediate transfer member to the recording medium, according to the number of selected image forming units or their disposition. | 2015-01-22 |
20150023679 | IMAGE FORMING APPARATUS - In a constitution in which a power source exclusively for primary-transfer is omitted and a predetermined voltage is generated in an intermediary transfer member, in a test mode in which a test voltage is applied to a secondary-transfer member in advance in order to obtain a proper secondary transfer voltage, in the case where the test voltage is low, a proper secondary-transfer voltage cannot be obtained in some cases. In a period of the test mode, the power source is controlled in order to maintain a Zener breakdown voltage, so that the proper secondary-transfer voltage can be obtained. | 2015-01-22 |
20150023680 | IMAGE FORMING APPARATUS - In a constitution in which a power source exclusively for primary transfer is omitted and a predetermined voltage is generated in an intermediary transfer member by a constant-voltage element, a high power source voltage more than necessary is applied in order to avoid primary transfer defect, so that a transfer member is deteriorated by energization in some cases. By detecting a current flowing into the constant-voltage element, it becomes possible to obtain a minimum power source voltage at which the intermediary transfer member is capable of maintaining a predetermined voltage, so that it is possible to avoid the energization deterioration of the transfer member. | 2015-01-22 |
20150023681 | IMAGE FORMING APPARATUS - A controller controls a voltage to be applied to the transfer member when there is a recording material having a predetermined largest width at a secondary-transfer position, so that a constant-voltage element maintains a predetermined voltage, whereby it is possible to prevent transfer defect due to short of a primary-transfer electric field at a primary-transfer portion when a toner image is secondary-transferred onto the recording material. | 2015-01-22 |
20150023682 | IMAGE FORMING APPARATUS - An image forming apparatus includes an intermediate transfer belt, a driving source commonly and rotationally driving the intermediate transfer belt and a second image carrier, a first cleaning blade rubbing at a first rubbing position, and a second cleaning blade rubbing a second image rubbing position. The image forming apparatus includes a lubricant supplying portion capable of supplying lubricant to the first or second rubbing position, a load detecting portion detecting a driving load of the driving source, and a control portion capable of executing a lubricant supplying mode of supplying lubricant to either one of the first and second rubbing positions on a basis of processing contents of a most recent predetermined number of times of image forming operations in a case where the driving load detected by the load detecting portion exceeds a predetermined value. | 2015-01-22 |
20150023683 | TERMINAL APPARATUS, IMAGE FORMING SYSTEM, AND NON-TRANSITORY COMPUTER READABLE MEDIUM - A terminal apparatus includes a driver. The driver includes a switching unit and has a dedicated mode and a standard mode, the dedicated mode making it possible to use all functions of a predetermined image forming apparatus, the standard mode making it possible to use a function common for plural image forming apparatuses. The switching unit performs switching from the dedicated mode to the standard mode in a case where it is determined that the dedicated mode is inapplicable after the dedicated mode has been started up. | 2015-01-22 |
