The invention relates generally to apparatus for electrostatic image development and, in particular, apparatus that implement a magnetic brush with a drum photoconductor. The tool includes source code sample files having an index section, a conditional statement section, and a subroutine section. The lift arm is pivotally attached to the frame. Moreover, it is possible to prevent deterioration of the image forming station due to a jam, and inhibit shortening of the life of the image forming station resulting from a jam. The first conductive element includes a first tooth configured to extend at least partially into an exterior surface of the self-contained spray can.
