摘要： In an image forming system, a lifetime management device calculates remaining lifetime of process units, a transfer unit, a secondary transfer unit, a belt cleaning unit and a fixing unit mounted on an image forming apparatus based on an operation amount thereof and a predetermined lifetime index. Based on the remaining lifetime and a predetermined replacement index, the lifetime management device determines whether any unit needs to be replaced, and, if any, transmits a replacement request signal to an external information processor together with a signal indicating remaining lifetime of other units via a communication line.

摘要： An image forming system includes an image forming apparatus that includes process units for different colors and a lifetime management device that manages lifetime information on each unit of the image forming apparatus. The lifetime management device counts the number of prints produced by the image forming apparatus with respect to each of photoconductor units and developing units in the process units, and measures an operation amount unique to the respective units. Based on the number of prints, service life of each unit and operation amount, the lifetime management device calculates the remaining lifetime of each unit.

摘要： A cleaning device cleans a discharge wire that discharges electric charge onto a discharge target. The cleaning device moves in a longitudinal direction oldie discharge wire. The cleaning device includes a first contact portion that contacts and cleans the discharge wire and a second contact portion that contacts and cleans the discharge wire. When the first contact portion and the second contact portion clean the discharge wire, the first contact portion and the second contact portion sandwich the discharge wire in a discharge direction in which the discharge wire discharges the electric charge onto the discharge target. The discharge direction is parallel to a radial direction of the discharge wire.

摘要： An image forming apparatus includes a developer conveyance device to transport developer, using a positive-displacement pump to alternately generate positive pressure and negative pressure by changing a volume of an internal space thereof, a destination developer container to which the developer conveyance device transports developer, a sensor provided to the destination developer container, to detect developer in the destination developer container, and a controller to control the positive-displacement pump according to a detection result generated by the sensor. The controller disabled detection of developer by the sensor in a non-detection period that starts from a stop of the positive-displacement pump.
