  We discuss the $t$ dependence of
  $J/\psi$ production in the region of $0< -t < M^2_{\psi}$. The forward slope
of the elastic differential cross section is calculated assuming a dipole-type
dependence for the gluon ladder-proton form factor. The $t$ dependence of
$d\sigma/dt$ is obtained using DGLAP evolution both for the elastic channel at
low $-t$ and for the inelastic channel at large values of $-t$, up to $-t\simeq
M^2_{\psi}$. Results are presented and compared with the relevant experimental
data.
