PROBLEM TO BE SOLVED: To provide an image sensor capable of reducing a dark current component caused by unstable reset of a photodiode, effectively suppressing a noise component caused by discordance of characteristics between pixels, and performing reset and transfer on specific levels even when the photodiode is not completely reset, a method of driving a transfer transistor. SOLUTION: The image sensor includes: a photosensitive pixels including a photodiode for generating a photoelectron, a transfer transistor for transferring the photoelectron to a diffusion node, and a reset transistor for resetting the diffusion node; a driving circuit for generating a driving switching signal with respect to the transfer transistor and the reset transistor; and an intermediary circuit for changing characteristics of the signal to drive the photosensitive pixel in a pseudo pinch-off mode.
