| 20080205913 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREFOR - An image forming apparatus that is capable of normally performing second side printing on a transfer material, even if the transfer material put on standby after completion of first side printing is pulled out by a user. A transfer material having image formed on its first side is fed until it is partly exposed to the outside of a printer, and is then fed to a refeeding path in the printer and further fed to a standby position prior to image formation on the second side of the transfer material. When it is detected that the transfer material caused to stop at the standby position is pulled out by a user, a warning to stop pulling out the transfer material is given to the user. | 08-28-2008 |
| 20080316541 | IMAGE FORMING APPARATUS, CONTROL METHOD THEREFOR, AND OPERATION APPARATUS OF EQUIPMENT - An image forming apparatus having improved installability and operability. The image forming apparatus has an operation unit thereof disposed on an arm extending from the apparatus and pivotable around a support member in substantially the horizontal direction, and has sensors for detecting the pivot position of the operation unit. An initial-screen setting screen determined based on the pivot position of the operation unit detected by the sensors is displayed on the operation unit. | 12-25-2008 |
| 20080317525 | BELT FEEDING DEVICE AND IMAGE HEATING DEVICE - A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. The belt feeding apparatus further includes a setting member for setting, when the belt is deviated from a widthwisely normal zone, an inclination angle of the supporting member to a return angle to return the belt toward the normal zone. The setting member also sets, when a predetermined time elapses from the belt returning to the normal zone, the inclination angle of the supporting member to a balance angle to keep the belt in the zone. | 12-25-2008 |
| 20080317526 | BELT FEEDING DEVICE AND IMAGE HEATING DEVICE - A belt feeding apparatus includes an endless belt; a supporting member for rotatably supporting said belt; and setting means for setting, when said belt is deviated from a widthwisely normal zone, an inclination angle of said supporting member to a returning angle to return said belt toward the normal zone, and for setting, when said belt is in the normal zone, the inclination angle of said supporting member to a balance angle. | 12-25-2008 |
| 20090028587 | IMAGE FORMING APPARATUS - An image forming apparatus includes a transfer unit configured to transfer a toner image based on image data onto a recording medium, a fixing device configured to thermally fix the toner image transferred onto the recording medium, a stack tray configured to stack a recording medium conveyed from the fixing device, and a controller configured to calculate based on the image data an amount of a toner on a top surface of the recording media stacked on the stack tray and an amount of a toner on a bottom surface of the recording media to be subsequently conveyed and discharged onto the stack tray and to control a recording medium discharge interval based on a result of calculating the amounts of the toners. | 01-29-2009 |
| 20090035005 | IMAGE FORMING APPARATUS - An image forming apparatus capable of preventing toner fusion between recording sheets, with a construction that does not require increase in cost and size of the apparatus and does not unduly lower productivity, to thereby offer high usability. For image formation on plural pieces of recording sheets, a CPU controls a recording sheet conveyance interval for a first set based on a detected amount of toner used for the image formation on each page, stores the toner use amounts for respective pages of the first set into a RAM, and controls the recording sheet conveyance interval for second and subsequent sets based on the toner use amount stored in the RAM for each page. | 02-05-2009 |
| 20090035006 | IMAGE FORMING APPARATUS - An image forming apparatus capable of preventing toner fusion between recording sheets to thereby offer high usability, with a construction that does not cause increase in cost and size of the apparatus and an undue reduction in productivity. In the image forming apparatus, a toner use amount in a partial region of an toner image transferred from an intermediate transfer belt to a recording sheet is detected. When it is determined that the toner use amount detected for the partial region is equal to or greater than a predetermined amount, a recording sheet conveyance interval is widened. | 02-05-2009 |
| 20100074645 | IMAGE FORMING APPARATUS AND IMAGE CONTROLLING METHOD - An image forming apparatus includes an image bearing member; toner image formation means for forming a toner image on the image bearing member; removing means for removing deposited matter deposited on the image bearing member; detecting means for detecting a toner image to be detected, formed on the toner image formation means; control means for controlling a toner image forming condition of the toner image forming means in accordance with a result of detection of the toner image to be detected by the detecting means; the apparatus being operable in a mode in which the removing means operates to remove the deposition, and the detecting means operates to detect the toner image to be detected, executing means for executing an operation in the mode; and an operating portion for manually starting execution of the operation in the mode by the executing means. | 03-25-2010 |
