Dry toner, method for manufacturing the same, image forming apparatus, and image forming method

An image forming apparatus comprising:

• an electrophotographic photoconductor;
• a charger for charging the electrophotographic photoconductor;
• a light irradiator for irradiating the electrophotographic photoconductor charged by the charger so as to form a latent electrostatic image;
• a developer for developing the latent electrostatic image to form a developed image;
• and
• a transfer for transferring the developed image to a recording material;
• wherein the developer contains a dry toner which comprises fine particles having an average sphericity of 0.93 to 0.99, and the content of the fine particles having a particle diameter of 2 μm or less in the dry toner is 20% by number or less.

An image forming process comprising:

• charging an electrophotographic photoconductor;
• irradiating light on to the electrophotographic photoconductor so as to form a latent electrostatic image;
• developing the latent electrostatic image with a developer to form a developed image;
• and
• transferring the developed image to a recording medium,
• wherein the developer contains a dry toner which comprises fine particles having an average sphericity of 0.93 to 0.99, and the content of the fine particles having a particle diameter of 2 μm or less in the dry toner is 20% by number or less.
