Image reading device and image forming apparatus |
摘要 |
A turning-on control unit causes a turning-on unit to apply to a light source an initial voltage when turning on the light source and to apply a rated voltage after the light source has been turned on. The initial voltage is higher than the rated voltage. An image-signal control unit controls analog signals to be input to an analog signal processing unit from a turn-on time point that is a time point at which the light source is turned on until a stabilization time point that is a time point at which output of the light source is stabilized. |
