Abstract

A toner for electrophotography contains at least one kind of cyclic compound selected from cyclic oligomers and cyclic polymers substantially having no terminal group, and the image forming device includes at least an electrostatic latent image carrier, an electrostatic latent image forming means for forming electrostatic latent images on the electrostatic latent image carrier, a developing means for forming visible images by developing the electrostatic latent images containing a developing agent for electrophotography, and a transfer means for transferring the visible images to a transfer material. Thus, the present invention provides a toner for electrophotography capable of providing well-balanced electrostatic property and fixing property during the image forming process in order to form images of high quality in a stable manner, and an image forming device.
