Abstract:
A development apparatus has a casing, a regulation plate, a smoky dust prevention sheet and a backup member which are fixed together onto the casing with a screw. The backup member sandwiches a fixed end portion of the smoky dust prevention sheet with the regulation plate. Therefore, the backup member suppresses detachment of the smoky dust prevention sheet from the regulation plate. Thus, the smoky dust prevention sheet is prevented from being detached from the regulation plate when the smoky dust prevention sheet is used in contact with a development roller in the state of being bended.
