摘要： An image forming apparatus includes a high-voltage power supply having a piezoelectric transformer. The power supply includes a positive output voltage generation circuit and a negative output voltage generation circuit. Each of the positive output voltage generation circuit and the negative output voltage generation circuit includes a piezoelectric transformer, a piezoelectric transformer driving circuit, an output voltage detection circuit, and a drive control circuit for outputting a control signal for controlling the piezoelectric transformer driving circuit using a signal from the output voltage detection circuit and an output voltage setting signal for setting an output voltage. The positive output voltage generation circuit and the negative output voltage generation circuit are simultaneously turned on when the output polarity of the high-voltage power supply with a piezoelectric transformer is switched.

摘要： An update value for updating a count value is changed in accordance with the time interval of activations of a fixing unit. Every time the fixing unit is activated, the count value is updated in accordance with the update value. The target temperature of the heater of the first rotary body is set in accordance with the updated count value to control the temperature of the fixing unit.

摘要： A catalyst carrier having a honeycomb structure made of metal sheets and used for a catalytic convertor for treating an exhaust gas of an internal combustion engine. The catalyst carrier is made of layers, each having a plain sheet, and at least one corrugated sheet applied on the plain sheet and having a width smaller than that of the plain sheet so that, laterally of the corrugated sheet, a portion of the plain sheet is not occupied by the corrugated sheet. The portion without the corrugated sheet is in face to face contact with a portion having a corrugated sheet on an adjacent layer, and as a result, a lateral engagement is obtained between the corrugated sheets of the facing layers, thereby preventing the layers from being laterally displaced along at least one direction.
