摘要： An image forming apparatus which includes a fixing device including a fixing roller, a pressure roller pressed into contact with the fixing roller, and a thermistor in contact with a non-paper-passage region on the surface of the fixing roller, the fixing roller incorporating a first halogen heater whose heat distribution based on the axial direction of the fixing roller is set such that heat in a middle region thereof is higher than heat in opposite-end regions thereof, and a second halogen heater whose heat distribution based on the axial direction of the fixing roller is set such that heat in opposite-end regions thereof is higher than heat in a middle region thereof; and a controller for controlling power supply to the first and second halogen heaters. The controller starts power supply to the first and second halogen heaters to start warm-up of the fixing device, and cuts off power supply to the first halogen heater for a predetermined period of time during the warm-up.

摘要： A transfer roller is spaced away from the outer surface of a photosensitive drum by a specified distance to prevent the abrasion and damage of the photosensitive drum by the contact of the transfer roller and the photosensitive drum. The transfer roller not in contact with the photosensitive drum can be formed to have a sufficient hardness without damaging the outer surface of the photosensitive drum. Further, since the transfer roller has a sufficient hardness, cleaning blades can be held in without damaging the transfer roller with a sufficiently large force without damaging the transfer roller, thereby securely scraping off toner and the line adhered to the transfer roller and preventing the rear surface of a transfer sheet from being smeared.
摘要翻译：转印辊与感光鼓的外表面间隔一定距离，以防止感光鼓通过转印辊和感光鼓的接触而磨损和损坏。不与感光鼓接触的转印辊可以形成为具有足够的硬度而不损坏感光鼓的外表面。此外，由于转印辊具有足够的硬度，因此可以以足够大的力将清洁刮刀保持在不会损坏转印辊的同时不会损坏转印辊，从而可靠地刮除调色剂和附着在转印辊上的线，并防止转印辊的后部转印片的表面被弄脏。
