Abstract
A multicolor image forming apparatus which includes a developer image forming unit to form an image using a developer and a transferring unit to transfer the formed developer image to a recording medium, wherein the developer comprises a plurality of dark developers and one or more light developers, wherein the dark developers and the light developers each include a binder resin having a weight average molecular weight from about 50,000 Mw to about 160,000 Mw, and wherein about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the dark developer is larger than about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the light developer.
Claims16
A multicolor image forming apparatus, comprising:
- a developer image forming unit to form a developer image using a developer;
- and
- a transferring unit to transfer the formed developer image to a recording medium, wherein the developer comprises a plurality of dark developers and one or more light developers,
- wherein the dark developers and the light developers each comprises a binder resin having a weight average molecular weight ranging from about 50,000 Mw to about 160,000 Mw, and
- wherein about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the dark developer is larger than about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the light developer.
A method for forming a multicolor image, comprising:
- forming a developer image using a developer comprising a plurality of dark developers and one or more light developers;
- and
- transferring the formed developer image to a recording medium,
- wherein the dark developers and the light developers each comprise a binder resin having a weight average molecular weight from about 50,000 Mw to about 160,000 Mw, and
- wherein about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the dark developer is larger than about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the binder resin of the light developer.
A developer image forming unit usable with an image forming unit, the developer image forming unit comprising:
- a plurality of dark developers and at least one light developer disposed within the developer image forming unit;
- a first binder resin corresponding to at least one dark developer;
- and
- a second binder resin corresponding to at least one light developer,
- wherein the first and second binder resin have a binder resin having a weight average molecular weight ranging from about 50,000 Mw to about 160,000 Mw, and wherein about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the first binder resin is larger than about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the second binder resin.
A developer usable with an image forming unit, the developer comprising:
- a plurality of dark developers and at least one light developer;
- a first binder corresponding to at least one dark developer;
- and
- a second binder corresponding to at least one light developer,
- wherein the first and second binder resin have a binder resin having a weight average molecular weight ranging from about 50,000 Mw to about 160,000 Mw, and wherein about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the first binder resin is larger than about 50,000 Mw to about 160,000 Mw of the weight average molecular weight of the second binder resin.
