Well, electronegativity is conceived to be the ability of an atom involved in a chemical bond to polarize electron density towards itself...

Explanation:

See this old answer and elsewhere.

On the other hand, ionization energy can be directly measured...and is the energy associated with the formation of one mole of gaseous cations and electrons from one mole of gaseous atoms.

#M(g)+Delta_"ionization energy"rarrM^(+)(g) + e^(-)#

Discounting the Noble gases, the more electronegative an element, the GREATER should be its ionization energy.
