A classic toaster (bread toaster) is mostly radiation with a little convection. The heating elements radiate their heat onto the contents of the toaster.
(In a "toaster over" there is much more convection when the oven is closed, and it functions like a conventional oven, cooking mainly with the trapped heated air.)
A toaster uses primarily conduction and radiation to cook food. Conduction occurs when the heating elements directly heat the bread touching them, while radiation happens when the heat is emitted to cook the outer surface.
Toasters primarily use radiation to heat up the bread. The heating element inside the toaster emits infrared radiation that transfers heat to the bread, causing it to toast. Some heat convection may occur as well, as the hot air circulates within the toaster chamber.
The three forms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.

The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a material, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
A toasted sandwich is heated through conduction between the bread and the heating element, as well as through convection as the hot air circulates around it. Radiation is also involved to a certain extent, but conduction and convection play the primary roles in toasting the sandwich.
