Abstract
A power supply apparatus includes a transformer including a primary coil and a secondary coil, a switching element connected in series to the primary coil, a first generation unit configured to generate a first voltage to be output to a first load from a voltage generated in the primary coil by turning on and off the switching element, and a second generation unit configured to generate a second voltage to be output to a second load from a voltage generated in the secondary coil by turning on and off the switching element. The first voltage has an absolute value smaller than an absolute value of the second voltage. The first voltage has a polarity different from a polarity of the second voltage.
