The developing roller/supply roller rotary bodies transmit the drive force inputted from the input rotary body to the developing roller/supply roller, respectively. The developing roller rotary body includes first and second drive input parts having different diameters. The input rotary body includes first and second drive output parts engaged with the first and second drive input part, respectively and having different diameters. The first drive output part is movable between a first position and second position. The first drive input part and the first drive output part are engaged when the first drive output part is in the first position. The second drive input part and the second drive output part are engaged when the first drive output part is in the second position. |
