Image forming apparatus

Abstract

An exposure head includes at least one light-emitting chip and a board. The at least one light-emitting chip includes a plurality of light-emitting portions for emitting light for exposing a photosensitive member from light-emitting surfaces. The at least one light-emitting chip is supplied with power from a power source via a power line. The board is on one surface of which at least one bypass capacitor connected to the power line and a ground and the at least one light-emitting chip are mounted. In a vertical direction perpendicular to the one surface of the board, a first height as a height from the one surface of the board to the light-emitting surfaces is higher than a second height as a height from the one surface of the board to an end of the at least one bypass capacitor farthest from the one surface of the board.
