    摘要： A drive apparatus is disclosed which is designed to switch/excite a plurality of excitation windings of a stepping motor in a predetermined order. Periodic velocity fluctuation data of the stepping motor is stored in a memory unit in advance. An arithmetic unit reads out the velocity fluctuation data stored in the memory unit. The arithmetic unit outputs a pulse train whose pulse rate fluctuates to have a phase opposite to that of velocity fluctuation obtained from the velocity fluctuation data. This pulse train is used as switching timing signals for switching/exciting the plurality of excitation windings in a predetermined order.

    摘要： A developing device includes a developer container, a developing roller, and a doctor member. The developer container contains a developer including a toner and a developer. The developing roller includes a developing sleeve bearing the developer, a magnet roller in the developing sleeve. The doctor member includes a regulating portion regulating an amount of the developer home on the developing sleeve to be a predetermined amount. The regulating portion is disposed with a first distance from the developing sleeve. The developing sleeve is disposed with a second distance from an image hearer, and when the developing sleeve bearing the predetermined amount of developer passes a vicinity of the image bearer, a value obtained by dividing the predetermined amount by the second distance is less than a threshold of occurrence of adherence of the developer to the developing sleeve.
