| 20080279734 | TONER MANUFACTURING METHOD, TONER MANUFACTURING APPARATUS, AND TONER - A method of manufacturing a toner by using a liquid dispersion in which a dispersoid containing a material for manufacturing a toner is dispersed in a dispersion medium, and containing a dispersant having a function of improving the dispersibility of the dispersoid, the method including the steps of: preparing the liquid dispersion, applying ozone to the liquid dispersion and/or a liquid dispersion from which at least a portion of the dispersion medium has been removed, and irradiating UV-rays to the liquid dispersion and/or the liquid dispersion from which at least a portion of the dispersion medium has been removed. | 11-13-2008 |
| 20110008079 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes an image carrier, a transfer roller, a transfer roller position detector and a controller. The transfer roller includes a concaved portion formed on a circumferential surface thereof with the concaved portion having a width in the circumferential direction larger than a width of a transfer nip formation area formed between the image carrier and the transfer roller in the circumferential direction. The transfer roller includes an elastic member disposed on the circumferential surface thereof. The transfer roller position detector is configured and arranged to detect a rotational position of the transfer roller. The controller is configured to stop rotation of the transfer roller in a state in which the concaved portion is located at the transfer nip formation area on the basis of the rotational position of the transfer roller. | 01-13-2011 |
| 20110033213 | TRANSFER APPARATUS AND IMAGE FORMING APPARATUS - A transfer apparatus includes a transfer belt being configured to carry an image, a transfer roller having an elastic layer and being configured to transfer the image from the transfer belt onto a transfer material, and a backup roller being configured to have pressure against the transfer roller with the transfer belt therebetween in order to form a transfer nip portion. The transfer nip portion includes a pressure-contact nip and a contact nip. A length of the contact nip is smaller than half a length of the pressure-contact nip in the rotational direction of the transfer roller. | 02-10-2011 |
