In an imaging apparatus, a two-dimensional surface on which imaging elements are arranged has a first region that includes one or more lines, and a second region other than the first region that includes a plurality of lines, each line including a light shielded region that is shielded from light and an effective region other than the light shielded region. In some examples, one or more configuration commands may be received at a controller for an SSD having one or more non-volatile memory arrays. If this data is sufficient for arming detection points, the exchange arms the detection points from which the first intelligent network services will be activated if the activation criteria are met during the call. At least two of loci of positions of impingement of the developer corresponding to said exhaust ports overlap each other.
