This invention relates to a magnetic toner (3b) composed mainly of a magnetic material and a binder resin, in which the difference between the softening point and the softening initiation temperature of said magnetic toner (3b) is made 5.degree. C. or more to provide a magnetic toner (3b) which is suitable for pressing transfer, particularly pressing transfer by use of an intermediate transfer member and capable of giving stable running characteristics without causing off-set phenomenon according to a conventional developing system without use of no special developing system and regardless of the photosensitive member employed as well as good image quality on a plain paper.

Process for transfer of a toner image utilizing a magnetic toner

An insulated magnetic toner comprising a binder resin and a powdery magnetic material, said magnetic material being iron or an alloy thereof having a coercive force of not more than 600e.

Insulated magnet toner

A method of fixing a toner image on a supporting member by bringing the supporting member supporting thereon the toner image into pressure contact with a fixing roller, wherein an elasticity improving agent for increasing the elasticity of the toner upon coming into contact with the toner is disposed on a member which comes into direct or indirect contact with the outer circumferential surface of the fixing roller. The elasticity improving agent is a material causing the reaction which increases the molecular weight of the binder resin of the binder and/or a reaction promoter for such a reaction. The elasticity improving agent is selected from a group consisting of:
