Abstract:	We have developed a model for MeV emission from blazars that involves the production of MeV gamma-rays through Inverse Compton (IC) scattering of electrons in the blob of a jet, with the UV photons of the accretion disk. The OSSE and the COMPTEL spectra of PKS 0528 + 134 have been fitted with the computed MeV gamma-ray fluxes of the above model. A good fit was obtained with electrons of Lorentz factor of 10^1.5 to 10^3 and a jet with viewing angle of <=15^∘ and an accretion disk temperature in the range of 2.0 to 6.0 x10^5 K.
