20150078766 | METHOD OF SUPPLYING DEVELOPING UNIT WITH TONER AND IMAGE FORMING APPARATUS USING THE SAME - A method of supplying a developing unit with toner and an image forming apparatus using the method are provided. The method may include supplying toner to a developing unit separate from a toner bottle in an image forming apparatus. The method includes: detecting a remaining amount of toner in the developing unit during printing; comparing the remaining amount of toner with a first reference value; if the remaining amount of toner is greater than the first reference value, continuing printing; and if the remaining amount of toner is not greater than the first reference value, determining whether to supply toner based on a preset mode. Deterioration of printing quality in a toner supply mode may be markedly reduced according to a user's settings. | 2015-03-19 |
20150078767 | FIXING DEVICE AND IMAGE FORMING APPARATUS - A fixing device that fixes a toner image carried on a transfer sheet onto the transfer sheet includes a fixing belt that relatively moves, with its surface being in contact with the toner image during the fixing operation, with respect to the transfer sheet, surface information detecting devices that determine surface information of the fixing belt, a surface condition changing roller that is arranged so as to be capable of coming into contact with and separating from the fixing belt and abrades the surface of the fixing belt in contact with the fixing belt, and a surface condition changing controller that controls the contact and separation of the surface condition changing roller with and from the fixing belt based on detection results obtained by the surface information detecting devices. | 2015-03-19 |
