Original Abstract Submitted
An image forming apparatus includes a rotatable image bearing member, a charging member, a developing unit, a cleaning member, and a supply container. In an accommodating portion of a new developing unit, an initial developer which is a developer in a predetermined amount is filled in advance. The initial developer contains toner particles of which charge polarity is a predetermined polarity, and to the toner particles of the initial developer, lubricant particles of a polarity opposite in charge polarity to the predetermined polarity are externally added. A supply developer which is the developer accommodated in the supply container contains the toner particles. An external addition amount of the lubricant particles to the toner particles in the supply developer is smaller than an external addition amount of the lubricant particles to the toner particles in the initial developer.
