Abstract:
1. An image forming apparatus configured to transfer development agent onto a sheet to electrophotographically form an image on the sheet, comprising: a driving unit configured to generate a driving force; a photoconductive drum configured to carry the development agent to be transferred onto the sheet and to be rotated by the driving force from the driving unit; an exposure unit configured to expose the photoconductive drum; a development roller configured to supply the development agent to the photoconductive drum exposed by the exposure unit to develop the photoconductive drum, while being rotated by the driving force from the driving unit; a feed roller configured to feed the sheet while being rotated by the driving force from the driving unit; a circumferential velocity switching mechanism disposed on a driving force transmission pathway from the driving unit to the development roller, the circumferential velocity switching mechanism being configured to switch a circumferential velocity of the development roller between a first circumferential velocity and a second circumferential velocity lower than the first circumferential velocity; and a controller configured to:
