    Abstract: A printhead includes a plurality of element substrates, each including a plurality of printing elements, arranged in the arrayed direction of the printing elements. Each element substrate includes a temperature detection element for detecting the temperature of the element substrate. The printhead includes a head control IC connected to each element substrate and configured to control driving of the printing elements integrated on the element substrates. The head control IC and the element substrates are connected via a head terminal by a signal wire for transferring a signal between the head control IC and each element substrate. A temperature detection signal output from the temperature detection element and an image data signal are multiplexed on part of the signal wires.
