Abstract
An image reading apparatus includes a light emitter configured to irradiate an original with light, a reading device including a line sensor and an amplifier, a detector configured to detect a temperature of the reading device, a sampling portion configured to sample a value of the analog signal output from the amplifier, a converter configured to convert the value sampled by the sampling portion into a digital value. The sampling portion is configured to sample the analog signal corresponding to a first light-receiving element included in the plurality of light-receiving elements at a first timing in a case where the temperature detected by the detector is a first temperature, and to sample the analog signal corresponding to the first light-receiving element at a second timing, which is later than the first timing.
