Abstract
Official abstract text for this publication.
An image forming apparatus includes a rotatable photoconductor and a developing device that uses a developer that exhibits magnetism, the developing device including a housing having an opening for development at a position facing the photoconductor, and plural developing rollers that are exposed through the opening in the housing, that rotate without contacting a surface of the photoconductor, and that are arranged without contacting each other in a direction in which the surface of the photoconductor rotates, wherein a minimum distance between an inner surface portion extending to the opening of the housing of the developing device and one of the developing rollers arranged close to the inner surface portion and a minimum distance between the housing and the surface of the photoconductor are each equal to or larger than a minimum distance between the developing rollers.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: a rotatable photoconductor including a top surface layer having a cross-linked structure formed by dehydration condensation of a charge-transporting monomer having a hydroxyl group; and a developing device that uses a developer that exhibits magnetism, the developer containing a toner obtained by dispersing fine particles that form the toner in a solvent containing water, causing aggregation, and conducting heating…
