Toner, developer, toner-containing container, process cartridge, image-forming apparatus and image-forming process

An image forming apparatus comprising:

• a latent electrostatic image bearing member,
• a latent electrostatic image forming unit configured to form a latent electrostatic image on the latent electrostatic image bearing member,
• a developing unit configured to form a visible image from a latent electrostatic image formed on the latent electrostatic image bearing member by use of a toner,
• a transferring unit configured to transfer the visible image to a recording medium, and
• a fixing unit configured to fix the transferred image to the recording medium,
• wherein the toner comprises toner base particles and secondary agglomerates, the toner base particles comprise a toner material that comprises a colorant and a binding resin, and the secondary agglomerates, which being formed of fine particles, each have a secondary particle diameter of no less than 10 μm.
