摘要:
A toner bottle driving device control method includes driving one of multiple toner bottle driving devices connected to a single toner container at a time, detecting abnormality of a toner bottle driving device being driven, determining a first abnormality phase of the toner bottle driving device being driven when a number of times the abnormality is detected exceeds a threshold, inhibiting the toner bottle driving device being in the first abnormality phase from driving until the first abnormality phase is resolved, driving a drivable toner bottle driving device containing a non-empty toner bottle when the toner bottle contained in the toner bottle driving device being driven is determined as empty, determining that the multiple toner bottle driving devices are in a second abnormality phase when each of the multiple toner bottle driving devices is determined as being in the first abnormality phase, and inhibiting image formation.

To cool a blade type server disposed in an air-conditioned room, the following arrangements are made. The first is at least one shell having a ventilation passage disposed in the air-conditioned room. The second is, the following are disposed in a ventilation passage: racks, in which blade type servers each composed of a case with slim boards housed therein are stacked; cooling coils each having a coolant passage and a cooling fin and cooling a passing air; and at least one fan unit having axial-flow fans placed therein and producing air currents in one direction. The third is the fan unit forces a cooling air to flow in one direction in the ventilation passage thereby to cool the servers in the racks. The cooling coils and racks are disposed alternately so that warmed cooling air after passing through the rack is cooled by the cooling coil and then cools the next rack.

摘要:
A first printed wiring board extends in the vertical direction within a first duct that extends in the vertical direction. A first axial flow fan generates airflow which absorbs heat from the first printed wiring board. Second and third ducts extends in parallel with the first duct. A fourth duct extends between the second and third ducts. A second printed wiring board extends in the horizontal direction within the fourth duct. A second axial flow fan is connected to the third duct. The second axial flow fan generates airflow which absorbs heat from the second printed wiring board. The electronic apparatus can be reduced in size.

摘要:
Airflow is introduced into an enclosure through an air inlet in an electronic component unit. The airflow runs toward a first electronic component. The airflow absorbs heat from the first electronic component. The first electronic component is thus sufficiently cooled. A second electronic component is mounted on a printed wiring board at a position remoter from the air inlet than the position of the first electronic component. An air intake opening is formed in the enclosure. The air intake opening is defined at a section of the enclosure opposed to the printed wiring board at least between the first and second electronic components. Airflow is introduced toward the second electronic component through the air intake opening. The second electronic opening is thus sufficiently cooled. In this manner, the first and second electronic components are cooled equally to the utmost.
摘要:
The invention provides a developing device, a process cartridge and an image forming apparatus that allow preventing abrupt variations in toner charge on a developing roller, caused by intrusion, into a nip, of toner accumulated above a regulating member of the developing device. A developing device using a one-component developer includes: a supply roller to which one-component developer is replenished, by natural motion, from a developer storing section. The bottom of the developing device is of a size that allows the supply roller to rotate. The developing device further comprises a filling member for filling a space above the regulating member, in order to prevent the toner located above the regulating member from intruding into a nip formed between the supply roller and a developing roller.
