An image forming apparatus comprises a latent image support which supports an electrostatic latent image. A charging unit charges a surface of the image support. A latent image formation unit forms an electrostatic latent image on the image support surface. A developing unit develops the latent image with toner to form a toner image. A transfer unit transfers the toner image from the image support to a recording medium. A transport unit transports the recording medium so that the image support surface is countered to a surface of the recording medium. The surface of the image support has a coefficient of friction ranging from 0.1 to 0.7 according to Euler belt method, and a difference between a speed of the image support and a speed of the recording medium is below 1%, and the image support has an outermost surface containing a filler and a binder resin.

An apparatus for driving a plasma display panel (PDP). The PDP includes a sustain discharge unit, a first charge and discharge unit, and a second charge and discharge unit. The sustain discharge unit maintains a voltage of a terminal of the panel capacitor at the sustain discharge voltage or the ground voltage. The first charge and discharge unit charges one end of the panel capacitor to the sustain discharge voltage or discharges one end of the panel capacitor to the ground voltage. The second charge and discharge unit charges the other end of the panel capacitor to the sustain discharge voltage or discharges the other end of the panel capacitor to the ground voltage.

The present invention relates to an electrical energy regulator system for a power supply bus, the system including:an electrical energy storage unit,a solar generator having a plurality of cells,a system for regulating the bus power supply voltage adapted to impose on each cell one of the following three states:a first state in which the bus is supplied with current,a second state in which the storage unit (BAT) is supplied with current, anda third state in which the cell is shunted,the cells being divided by the bus voltage regulator system into:a first group in which at least one cell supplies power to the bus and one cell is assigned to regulation of the voltage of the bus and is in its first state only when maintaining a nominal bus voltage requires a top-up of current, anda second group in which at least one cell is either in a second state or in a third state, as a function of a required charging current of the storage unit, the number of cells in the second state being a function of the required charging current.The system further includes a system means for regulating the charging of the storage unit which assign at least one cell of the second group to supplying power to the storage unit (BAT) and one cell of the second group to regulating the voltage of the storage unit, the storage unit charging voltage regulator cell being in its second state only when maintaining a nominal charging voltage requires a top-up of current.

The invention provides a public charging management system which is applied to public equipment provided with power sources. The public charging management system comprises a communication unit, a power source converting unit, a billing unit and a central control unit. The public charging management system is communicated with a server through the communication unit. The server is provided with an online bank payment system. The power source converting unit charges a to-be-charged device connected with a charging interface. The billing unit computes cost according to charged electricity quantity. The central control unit generates an electronic payment bill, sends the electronic payment bill to the server according to the computed cost, and logs in the online bank payment system so as to enable a user to pay an unpaid electronic payment bill. Further provided is a charging method. The public charging management system and the charging method facilitates charging and paying by the user.

A charger for an electronic device that charges a rechargeable battery of the electronic device. The charger includes a detection unit, which detects connection of another electronic device to the electronic device through a communication cable including a power supply line. A charging unit charges the rechargeable battery with power supply voltage from the power supply line. A measurement unit acquires a measurement value indicating a degree of a voltage drop of the power supply voltage occurred when the charging unit performs charging. A control unit instructs a charging current value for charging the rechargeable battery with the charging unit. When the detection unit detects connection of the other electronic device, the control unit monitors the measurement value while instructing the charging unit to increase the charging current value from an initial current value and determines the charging current value based on the monitored measurement value.
