Image forming apparatus with reduced flexural deformation of endless belt

摘要

A toner image onto a print form by pressing a photosensitive material belt against a transfer plate through movement of a transfer opposite roller. The photosensitive material belt running in a direction orthogonal to the supply direction of the print form on a transfer plate. The photosensitive material belt is stably maintained at a region completed for transfer in an attitude following the upper surface of the print form.
