Abstract
A method for driving a self-scanning light-emitting element array, in which a power consumed in a write signal limiting resistor provided outside a chip to suppress a temperature rising of an optical writing head. The difference between High-level and Low-level in a circuitry in the driver circuit for controlling the light-emitting portion in the chip is set so as to be lower than the difference between High-level and Low-level in a circuitry in the driver circuit for controlling the transfer portion in the chip. A power consumed in a write signal limiting resistor provided outside the chip may be decreased to suppress the temperature rising of the optical writing head.
