\maketitle\abstracts{
 The measurement of the polarized gluon distribution
 function $\Delta g(x)$  from photon gluon fusion processes in 
 electron proton deep inelastic scattering producing
 two jets has been investigated. The study is based on the MEPJET
 simulation program.
 The size of the expected  spin asymmetry
 and corresponding statistical uncertainties
 for a possible measurement
 with polarized beams of electrons and protons  at HERA 
 have been estimated.
 The results show that the asymmetry can reach a few percents.
