摘要： A transfer sheet detect sensor for detecting the presence or absence of a transfer sheet is disposed between a point of contact where a developing device for developing an electrostatic latent image formed on an image carrier to form a toner image is contacted with a transfer roller in a transfer portion and a point of tucking provided just upstream of the contact point where the transfer sheet is tucked into the image carrier just upstream of the contact point, the transfer roller is disposed such that it can be contacted with and retreated (separated) from the image carrier, and a cleaning roller is provided such that it can be contacted with the transfer roller while the transfer roller is retreated to its separated position, whereby a given cleaning voltage is applied to the transfer roller when the transfer roller is cleaned by the cleaning roller.
摘要翻译：在用于显影形成在图像载体上的静电潜像的显影装置以形成调色剂图像的接触点之间设置用于检测转印纸的存在或不存在的转印纸张检测传感器，其中转印辊与转印辊接触转印部分和提取点刚好在接触点的上游位置，转印片材刚好在接触点的上游被卷入到图像载体中，转印辊被设置成使得其可以与接触点接触并从其中退出（分离）图像载体和清洁辊被设置成使得其可以在转印辊退回到其分离位置的同时与转印辊接触，由此当转印辊通过清洁进行清洁时，将给定的清洁电压施加到转印辊上滚筒。
