Abstract
An optical writing head in which the number of bus lines to be derived may be decreased by using a self-scanning light-emitting element array is provided. A &PHgr;1 bonding pad of each SLED chip is connected to &PHgr;1 bus line via a resistor R1, and a &PHgr;2 bonding pad of each SLED chip is connected to &PHgr;2 bus line via a resistor R2. &PHgr;S bonding pad is connected to a &PHgr;S bus line via resistor RS, and VGA bonding pad is connected to VGA bus line. &PHgr;I bonding pad of each SLED chip is connected to a corresponding one of terminal &PHgr;I(1)-&PHgr;I(56) of a connector.
