Abstract
A structure and method for mounting recording units in an electrophotgraphic recording apparatus wherein collar members provided at both ends of a photosensitive drum or a sleeve are disposed to come into tight contact with the opposing sleeve or photosensitive drum to secure a uniform developing gap therebetween and wherein a developing unit opposed to a drum unit is pivotably supported at a longitudinal central point of the developing unit. Even when the photosensitive drum is biased in its central axis, the above pivotable movement of the developing unit enables the sleeve to flexibly follow the axis biasing movement and also enables the rotational axes of the photosensitive drum and sleeve to be kept in their parallel relation, whereby the uniform developing gap can be positively secured at all times along the longitudinal direction of the photosensitive drum, and this can contribute to the stable picture image recording operation.
