Abstract
A heater includes an irradiator configured to irradiate a heating object including a liquid attachment region, onto which a liquid is applied, with an active energy ray, and circuitry configured to control an output of the active energy ray emitted from the irradiator to an edge portion in the liquid attachment region of the heating object to be larger than an output of the active energy ray emitted from the irradiator to a non-edge portion in the liquid attachment region excluding the edge portion.
Claims15
An irradiation unit comprising:
- an irradiator configured to irradiate a liquid applied on a liquid attachment region in an irradiation target with an active energy ray to dry or cure the liquid on the liquid attachment region in the irradiation target;
- and
- circuitry configured to control an output of the active energy ray emitted from the irradiator to an edge portion in the liquid attachment region of the irradiation target to be larger than an output of the active energy ray emitted from the irradiator to a non-edge portion in the liquid attachment region excluding the edge portion.
